Scrolling stutters on 120Hz screens

  • Hello,

    I've noticed that the Opera app on Android stutters quite a lot when scrolling, at least on a phone with a 120Hz screen (I use a Galaxy S21).

    I've done some research and I've found out that Chromium browsers generally don't play nice with 120Hz screens, but that this can be fixed by disabling the "Android SurfaceControl" flag. I tested this with the Chrome browser and it indeed worked. However, with Opera (which is my preferred browser), we cannot access this flag. Would it therefore be possible to either (i) simply fix this issue, or (ii) give us access to this flag so that we can disable it?

    Many thanks for any help you can offer.

  • @japs yes i also face this issue.
    No fix for this except waiting for opera team to do something about this

    Could you try Opera Mini to see if Opera Mini doesn't have this problem?

    Opera Mini uses WebView only under a surface.
    Opera is a full browser and only parts are WebView
    Opera doesn't have a surface and communicates directly with your input, like you scrolling by touching the screen.

    If you touch the screen, a lot of events are happening, these build up in the message que. If the message que gets overloaded at the main thread the application Opera doesn't stutter but actually freezes its main thread only. Although you perceive this as stutter indeed.

  • @ginger1984 opera mini doesnt have such issue. Its lag a bit while loading page only. But textwrap doesnt work for me ( Samsung S21+ exxynos)

  • @mrxyzl this happened before. Opera Mini uses Chrome Android WebView but therefore cannot interface directly.

    Next test, try Google chrome, does it stutter like Opera Mini or does Google chrome stutter like Opera full browser.

    In the past when Google started stuttering eventually Opera full browser did because Google Chrome and Opera full are from same code base an open source project.

    Please let me know.

    Meanwhile repeat the test before 120 hz and after 60hz in phone display options.

    If 60hz display option didn't work read this:

    Hope to hear from you. This happened before.

  • @ginger1984 as stated at the first post, chromium/chrome also have this issue but can be fixed by disable surfaces control flag

  • @mrxyzl but also with display at 60 hZ test?

    But because you found out which setting needs to change you pointed out something I would like to get back in Opera too.

    In the past Opera had so many config options and one day it was gone. Hope it gets back since with Chrome it's here too to change a few things, but I don't use chrome much.

    As you read the other thread about stuttering you could try to wipe cache and reboot, especially if you received a WebView update with Google Play.

    Most questions of why have been answered in the thread about stutter, it took 2 years. But suffice it to say that Samsung did a 'little' change. (Samsung slowed down other browsers and paid a fine dor it in Italy, because all browsers were affected except Samsung browser like Microsoft once paid a fine for destroying other browsers)

    See this, could try to read if you see a familiar preface.

  • I can confirm that Galaxy Tab s5e is also affected seriously unfortunately again with this bug.

    Chrome before switching flag has identical stutter behavior.

    Then in chrome://flags disabling the "Android SurfaceControl"

    Chrome now suddenly is very smooth in scrolling.

    Al Opera has to do is considering giving the flags options back as they existed in the past.

    opera://flags

    The biggest problem with Android is for me that it has continually regression in bugs, and these bugs you can wait for easily 2 years to be fixed.

    I will try this fix in Chrome at my mobile phone to see if it has similar results since then more devices are affected.

    Also a lot of phones like Xiomi seem to be affected when reading about this flag that proves just a tiny thing can make it work smoothly.

    I don't like Chrome itself it has continually Microsoft office like digital assistant popping up which a lot of people knew as Clipy Office assistant. Besides that nowadays when visiting a website it's pushing popup for cookies, selecting lists of cookies, floating ads while scrolling, then a lucky you win advertising, then subscribe to website then login button to read more, then finally reading an article, yes that is Google chrome, oh I forget Google says if I want to get automatic translation at every page...

  • @mrxyzl this occurred previously. Drama Mini uses Chrome Android WebView yet in this way can't interface straightforwardly.

    Next test, attempt Google chrome, does it stammer like Opera Mini or googles chrome falter like Opera full program.

    In the past when Google began stammering in the long run Opera full program did on the grounds that Google Chrome and Opera full are from same code base an open source project. 👈

    Kindly let me know.

    In the interim recurrent the test before 120 hz and after 60hz in telephone show choices.

    On the off chance that 60hz showcase choice didn't work read this:

    Desire to hear from you. This occurred previously.

  • @wiviwol947 All Chromium based browsers now have this bug. That's a lot of them.

    Here is an excellent example at the open source chromium development website.

    https://bugs.chromium.org/p/chromium/issues/detail?id=1057459

    They have included a good example video. But as you read some browsers have the flags that only one of needs to be set to disabled and it suddenly works smooth as it should.

    Probably someone needs to forward it to the chromium development website too.

    The reason they say flags disappeared is because after a certain amount of time a flag is disabled automatically in the building process.
