  • cesisco do you feel the problem is solved for those devices as of r248?

    The APK overall performance is not flawless, but is very similar to chrome on that same device, and that's the point that we should focus on.

    cesisco do you have videos showing the level of jank for those devices?

    If I can get the example projects used I can test them on iPhone and we can compare the platforms.

    Hey Vikingvikingviking, I don't have videos, but after r248 , the difference between Chrome mobile and APK is minimal on these devices using the C3 project from my first post on this thread.

  • Does anyone know the state of the list of devices that we tried to compile?

    It could be good to send it to the chromium devs even though it may only contain one device 😅

    I hope the issue will be solved. It's a bit problematic to release on android as long as the jankiness exists.

    Let me know if I can help, even though I don't have any android devices.

    These were the devices I collected, but the Jank is much better after beta r248

  • Thanks  CascadeGames

    Wow, sorry Ashley for not testing with the latest C3 release from the beginning, but usually users use Stable versions for release their final builds.

    Should we consider that there's no relevant difference between Chrome mobile and APK now?

    Just tested and its much better.. its not jank free but is indeed better.

    Thanks klabundee I'll check in other devices and with a complete game too.

  • Just a heads up, make sure you do any testing in r247+, since we fixed a separate issue potentially causing jank in the WebView in that release.

    Thanks Ashley I was using the stable version, but it still Janking on the latest beta.... or maybe I can't trust my eyes anymore after so much testing.

    Hey klabundee can you please test the new APK with the latest C3 beta on your Galaxy S9 SM-G9600 Android 10 , if you have the time please.

    I totally agree. I interpreted your earlier post as you were on your way to shut down the thread. I just thought better to send what we got so far.

    Just posted it now

    bugs.chromium.org/p/chromium/issues/detail

  • > If I can't get more devices, I'll assume that this problem is not relevant and it's only affecting a few devices, so continuing this thread is meaningless.

    We could always send the findings collected so far, who knows it could lead to a solution on those devices

    They only have easy access to Pixel devices(where this problem is not present), so it would be better to give them a substantial list of devices so there's a higher chance of this being tested.

    And I thing, it would be important to know if this is a problem on high-end/new Android devices apart from those Pixel devices

  • Hey guys, I need more information about devices that can run the HTML sample version(on this thread) smoothly on Chrome mobile, but can't run the APK at the same level of performance, so chromium engineers can run tests on those devices.

    If I can't get more devices, I'll assume that this problem is not relevant and it's only affecting a few devices, so continuing this thread is meaningless.

    I just have these devices for now.

    Samsung Galaxy A20e (OS 10)

    Samsung Galaxy S9 SM-G9600 (OS 10)

    Redmi 5 (OS 8.1.0)

    Alcatel A3XL (OS 7.0)

  • Thank you guys.

    I think It's important that we can collect a bigger list of devices that can run the HTML versions smoothly but can't run the APK properly, so their engineers can test on the actual device.

    This was stated by a chromium project member, and probably not everyone is aware of:

    "WebView's rendering pipeline is not the same as Chrome's and is likely to be slightly slower in general on any device. Because the way it renders is different, it may provoke different behaviours/optimisations/bugs/etc from GPU drivers as well, which may also affect performance. If we have a reproducible case where there's a large difference we can investigate further."

    So, that could be the final explanation for the bad APKs performance, but like he said( and Artpunk too) their Pixel devices can run the APKs smoothly, so I think it's still relevant to collect the information about the devices that can't run the APK well so they figure out the performance difference.

    And for me it's not that obvious why a Pixel device performance would be so much better than a medium-range Samsung Galaxy

  • Hey tarek2 thanks

    The bad performance was there before I included the texts, so I included them to give me clues on the bad performance ;)

    But  you are right I can replace for Spritefonts

    Just to clarify, I need the info about the devices that run the APK poorly, but can run the HTML version smoothly, to figure out why is he difference so big. In your case it runs poorly on both.

  • On my test Runs really really bad instead of just stutters it does big jumps lugging:

    Galaxy S8

    SM-G950F

    Android 9

    Render: webgl2

    Not sure if this is normal but why does it print info like:

    AppleWebkit/537.36

    Safari/537.36

    etc...

    When the phone is a Samsung Android

    Aslo, the Web version runs quite badly on the same phone so I'm not sure if this is just a problem with the APK or the whole Android, as both run the same (APK & Web)

    Thanks for the feedback.

    That info is the user agent.About the Web version running poorly, do you have the Chrome browser updated?
