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.

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.
Coud be possible that this bug only exist on certain android devices.
The stutter scrolling behaviour also exist on my Huawei honor 6x.
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
