I've been working around compositor implementation flaws by using a custom EDID file. Now the compositors I've tried (Mutter, KWin, Sway) run at the correct 144 Hz, however xwayland clients still only refresh at 60 Hz. This is bad because if using a monitor with no even multiple of 60 Hz (like 72, 75, or 144 Hz monitors), there is stutter instead of smooth playback. And I guess many common apps will be running through xwayland for quite some time. I can also confirm the problem running glxgears, which runs v-synced and prints 60 FPS to the console.

You might be interested in this one Bug Report for wanting to add different refresh rates to mutter: https://bugzilla.gnome.org/show_bug.cgi?id=781296 Reply at: https://bugs.launchpad.net/ubuntu/+source/xorg- server/+bug/1746163/comments/1 ------------------------------------------------------------------------ On 2017-10-18T13:25:21+00:00 Michel Dänzer wrote: (In reply to stevengruspier from comment #1) > You might be interested in this one Bug Report for wanting to add different > refresh rates to mutter: https://bugzilla.gnome.org/show_bug.cgi?id=781296 This is an Xwayland issue, the Wayland compositor has nothing to do with it.
