--- Comment #3 from Robert Mader <robert.ma...@posteo.de> --- Some more notes here: we just enabled the frame callback based vsync emulation by default on the Wayland backend in Firefox 85. The Wayland backend is not enabled by default yet and 85 will only released in the end of January, however users explicitly enabling it and running nightly or soon beta will run into this issue. Therefore I personally am quite eager to see it resolved :) The benefit of using frame callbacks are twofold: on one hand we can run at refresh rate on non-60Hz monitors, on the other we can stop rendering when the compositors stops sending callbacks, for example when the window is completely covered, reducing power consumption. So overall quite desirable. I'm do not know how kwin handles callbacks, but I'd like to point out to how mutter initially handled this: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/839/diffs?commit_id=d49d10b14f4e0fa80e6867979b26fab383610b39 While the solution is not optimal (and thus was later replaced with a more comprehensive solution mentioned above already), something similar might work for kwin as well - and in mutter it was only 4 lines.
