Galaxy S8 has it too. Both in Chrome and Opera. But not in a Webview based browser. I have an Exynos SOC and not a Quallacom unfortunately. Yes it's a Samsung thing. At XDA people noticed it too. Alone the Samsung browser working great is unfortunate.
At these devices Opera Mini does use Webview and yes Webview then it works very smooth.
At my Samsung Quallacom SOC Tablet it works fine, but not at Exynos SOC based phone or tablet.
Rumor has it people with Samsung Galaxy S10 with Exynos SOC have it too.
I prefer Opera, but on Exynos SOC of Samsung it's not Opera.
I am sorry. Since Opera and even Google cannot, without working together with Samsung about Exynos specific details on it, undo this.
If I buy another Samsung, I think I will select it not to have Samsung it's own SOC, the Exynos.
I don't believe Samsung doesn't know. But all Exynos users are probably affected.
Keywords: Samsung Galaxy Scrolling Stutter Chrome Opera
Note: This is not specific to all models, but only certain Samsung SOC, mainly Exynos.
I replied at your YouTube and I recognize it, since it is like as if Scrolling happening only at say 10 frames per second. I can really visually count the number of frames.
Kinetic Scrolling isn't really noticable though.
Sad story, ironically since Chrome has it too, and Chrome is also Webview in Android, questions are;
Why does an application not known as a browser but using just Chrome still works smooth?
Well, I would sit at the table with Samsung if I were Google. Since Google it's browser suffering too, only Samsung Browser or Opera Mini ( used Webview ) are working smooth.
And yes I factory reset, everything, it took months to understand.
It's Samsung doing something. At least at Exynos SOC. Not all Samsung devices have Exynos so Opera HQ team might find perfect smooth Scrolling at supposed same device, though it has same name it might have different SOC.
@samstabauser said in Bad scrolling:
no difference between kinetic-scrolling and normal scrolling style? hardly to believe.
by the way
I use a Samsung Tab A 2016 tablet (T580) with current Android 8.1 but Andorid 7 was the same.
https://www.notebookcheck.net/Samsung-Galaxy-Tab-A-10-1-2016-Tablet-Review.171710.0.htmlCoud be possible that this bug only exist on certain android devices.
The stutter scrolling behaviour also exist on my Huawei honor 6x.
https://www.notebookcheck.net/Honor-6X-Smartphone-Review.207056.0.html
Thats why i still use older Opera for android apk´s on this device too.Should really be investigate by software engineers.
one more thing 30 vs 60 fps

thank you for your reply. It´s so sad - they still just don´t fix that issue.
One think i have to add.
it is NOT only a Samsung Chrome opera problem in my opinion,
cause it also exist on my Huawei Honor 6x with Hi-Silicon Kirin 655 SoCGood the XDA people also recognise this problem.
Just translate this webpage to your language...
https://www.androidpit.de/samsung-galaxy-smartphones-apple-iphone-nach-updates-langsamer-strafethere are words for such behaviour - planned obsolescence
Fun fact - as you wrote Samsung highend smartphones S8 and S10 are also affected. So it´s not only a budget class problem.
Glad i/we have android apks to install an old version to fix this issue.

@samstabauser Samsung paid a 5 million fine for artificial slowing down I read, oh man sad man, that did not solve the problem. I know installing a custom ROM disables the detection of browsers not allowed to run normally, but that voids KNOX and means no banking or Netflix. I try to explain in pseudo code what is happening.
#define CPU_SLOW 1
#define CPU_OVERCLOCKED 2
#define CPU_NORMAL 0int FoolUserToBuyNewPhone(char * foregroundProcesName)
(
if( !strcmp(foregroundProcesName,"Antutu Benchmark") )
return CPU_OVERCLOCKED;if( buildDate ≥ releaseDate + 1 year ) {
if {IsNotSamsungBrowser() && !IsWebView() )
return CPU_SLOW;
else
return CPU_NORMAL;return CPU_NORMAL;
}At XDA they noticed it very obviously, it's a tiny piece of code only that detects which kind of browser but let's WebView unaffected. This can be proven at my S8 since WebView is same as Chrome and Opera Mini, but Chrome which supplies the WebView to Samsung too is unaffected, but if it's called Chrome than it's very slow.
At XDA developers there are a few tech specialists and they too are a little upset and frustrated.
My solution is accepting Samsung browser, since it's not Opera or Google fault. Microsoft did this with Netscape and Firefox a long time ago.
In the example is also shown the detection of benchmark software. Which has been proven at Linux Techtips and XDA too.
Sad news, welcome to the Samsung club. Lineage OS ROM is now only solution, but you will loose banking and Netflix and Camera with exception of primitive basic Camera functions.
🥺
Time to go to XDA developers, maybe people,... ooh well
This is Samsung it's way to say it's time to buy a new Galaxy for 750 Euro.
I don't like it, how can I sell this phone without being dishonest? I use it for browsing and it wants Samsung browser unless I or the buyer learning to live with a stuttering experience.

Google's News app has this issue as well. This proves your theory so the Chrome browser engine causes the problem.

pseudo codeif then else
or case ??
This is Samsung it's way to say it's time to buy a new Galaxy for 750 Euro.
I won´t do that
btw i installed the Samsung browser on my huawei Honor
THAT produce stuttering too, i can tell you. Someone on google playstore comment this too and Samsung reaction was.
Other device manufacturer doesn´t have that technology to deliver the Samsung experience. I can´t believe they really put such a reaction online.But opera shouldn´t be like this cause it´s chinese too.
Hope firefox for android will get a better GUI + more fluid reaction behaviour . It´s just a mess on android. -

My Samsung Galaxy S3 from 2012 spare phone with Lineage OS Nougat works fluently in scrolling. Only because of its 700 megabyte memory I can open 3 websites only simultaneously. But hey it's faster than my 4000 Megabytes memory Samsung Galaxy S8.
I tried scrolling with Samsung Browser in pop-up over tiny window over Opera. In developer options of my phone I enabled GPU profiler, and Webview seems detached from directly getting touch screen input and works very well like Opera mini is smooth.
Samsung browser has a detached from touchscreen directly like GPU profile too.
Communicating touchscreen events directly to Opera or Chrome main thread that is also the viewport seems to be culprit here.
I suggest Opera developers to try a simple overlay window that passes touch events forward to the web viewport in NDK since directly communicating with NDK is problematic. Not only for Opera but for Yandex, Chrome, Brave browsers...
Opera could do this as Opera Dev version e.g.
I turned almost into Steve Jobs. Steve was known for forcing the development team to look for another better way.

@boti99 Message pump overflow from touchscreen events. @miyukiwork maybe you can forward this to your team deciding what is important.
Stutter is observed in such a stable way, that it seems touch events overflow the message que. When this happens, touch events are dropped. Then browser viewport stops responding a short time, perhaps 100 millisecond. Then the touch events message que is ready to be filled with new touch events, and it happens again. As in native development kit Opera seems to not be able to filter out unimportant messages fed from the touch screen. Like it's not necessary to process for example duplicate touch events. This is not happening at all devices.
At least it's such a stable stuttering and so depending on touch events, ask your team for studying how many events a touchscreen can send in so little time. It's rather Opera now wants to process all events but that is unadvisable.
A millisecond pause for example in processing the message pump from touchscreen events can prevent this flood.

@ginger
thank you for your support at this point.
I appreciate all your input in this issue.
Hope we really whip the Llama's A..
I still prefer the opera for android GUI.P.S.:
My last iOS device was an iphone 4s with iOS 8 and 9.
What i really dislike is: Safari does not support kinetic scrolling. at least till iOS 9.3.5
Does anyone know if this issue is still in current iOS versions? -

yes same problem here. i already wrote an email to opera support, no response.
my Solution:
Uninstall Version 46 and newer (what you get right now from google playstore is v. 48.x) and go back to Version 45!
Where do you get official opera Final apks?
https://get.geo.opera.com/pub/opera/android/4500/Than scrolling websites while your finger is on the screen is as -smooth- as only kinetic scrolling is right now in opera for android browsers...
... and like it is on the homescreen. 60 fps - i likealternative try Samsung internet browser.
technical info:
i think its a problem that is called Enable resampling scroll eventsOpera for android, google chrome and Samsung internet browser are using chromium as engine...
Hope they will fix this annoying bug and bring back project butter on our surf-tablets and smartphones.

My Samsung S5e tablet and Galaxy S8 both are unusable with Opera, Chrome, Edge, Yandex.
I am forced to use Samsung browser. When I got the 2019 Samsung S5e tablet everything worked great. However I am in vendor lock in to use Samsung browser now.
It's legal to force people to use Samsung browser since Samsung is not a monopoly.
Don't like it. Opera version you mentioned is the latest chromium based build that works smoothly.
Opera should open their eyes, Samsung is forcing to use Samsung browser.
It's not Opera it's the Samsung firmware. Opera has no chance against a bigger Samsung anyway.
Yes artificially slowed stuttering browsers unless it's Samsung browser at a Samsung device.
I think Opera does care but simply it's a matter of hear no monopoly, see no monopoly, ...
Here is a open letter at XDA developers about Samsung and monopoly at Samsung devices

@samstabauser indeed after 2 years Opera finally found out where in the gigantic open source chromium code, fluent scrolling can be enabled. Tab s5e 2019 and galaxy S8 2017 working with smooth scrolling.

Since 2021 opera browser is stuttering mess at galaxy devices of samsung. I suggest people to forget about Opera browser as a viable browser at samsung devices. The last time it took opera years to understand that samsung wants to get opera done away. Don't waste your time for opera again. Samsung doesn't allow Opera. Install samsung browser or Google browser. Forget about opera.
Spare your time, opera has no future except export of bookmark and import into samsung galaxy browser.
Don't waste your time at opera anymore.
Opera isn't allowed at smooth scrolling.
If you don't have a samsung you probably aren't affected.
Forget opera at samsung devices. Samsung doesn't want it.

Managed to solve it. After every firmware update you have to do the following. Which most people won't understand.
Clear Opera App cache
Reboot into official Samsung recovery and wipe cache.
BootupMost people including me will give up before especially wiping cache from official Samsung recovery.
But I did wipe it. And everything is smooth for now. Opera seems to be the first app that will stutter but you'll have to clear Opera cache and wipe cache partition. At Samsung devices.
Remember not all people are understanding to go into recovery mode and wipe cache partition. It worked fine but I consider it luck.
Did you update Android webview?
Did you update Opera?
Did you update play services?If so first reboot and if it doesn't work wipe cache which most people won't understand.
At xda you can find how to wipe cache for a device and that is very difficult for average user.
For now opera is smooth again until webview and firmware updates and so on and on and on.
