Description

Can you try to enable HW acceleration, set layers.acceleration.force-enabled to true at about:config and restart the browser. Also can you attach your about:support? layers.acceleration.force-enabled=true is definitely an improvement and now for example the lips and synced with the audio, but I still get small "jumps" in the video. The playback is smoother in X11. Created attachment 1624348 [details]
about:support with layers.acceleration.force-enabled=false
Can you try standard trouble shooting steps [1], especially: 1) Create a fresh new profile with disabled addons 2) Test Mozilla binaries with Wayland Thanks. [1] https://fedoraproject.org/wiki/How_to_debug_Firefox_problems?rd=Bug_info_Firefox Created attachment 1625483 [details]
Firefox on Wayland about:support on new profile
The same behaviour with new profile and addons disabled.
Can you also try latest Mozilla binaries to check it's not Fedora specific issue [1]? Thanks. [1] https://fedoraproject.org/wiki/How_to_debug_Firefox_problems?rd=Bug_info_Firefox#Testing_Mozilla_binaries I wonder if that's https://bugzilla.mozilla.org/show_bug.cgi?id=1542808 - do you have a monitor which does not use 60Hz frequency? Ok, it looks related to the resolution. I do the tests with Youtube 1080p60 videos. This is my setup: $ xrandr XWAYLAND0 connected 3072x1728+1920+0 (normal left inverted right x axis y axis) 600mm x 340mm 3072x1728 59.94*+ XWAYLAND2 connected 1920x1080+0+772 (normal left inverted right x axis y axis) 340mm x 190mm 1920x1080 59.96*+ Laptop display: 1920x1080 resolution. Video playback is very smooth, even to full screen. Monitor: 4K resolution 60 Hz, with 125% scaling. The playback is only smooth if the Youtube video is in the default size (although subjectively not as smooth as in the laptop display). In bigger sizes like cinema mode or fullscreen, the video lags. In X11, the playback is always smooth on both monitors at any size. I've also tested the Mozilla binaries version 69.0.3 with a clean profile and the results have been the same. It's the factional scaling of Gnome Shell. With a 100% o 200% scaling this problem doesn't happen. This message is a reminder that Fedora 31 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 31 on 2020-11-24. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '31'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 31 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. Fedora 31 changed to end-of-life (EOL) status on 2020-11-24. Fedora 31 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
