I have mostly used my AMD 2400G APU/8GB memory HTPC system connected with hdmi to LG's 4k tv. My linux distro is Mageia 7 with
- gnome-3.32
- kernel-5.4.6
- mesa-19.3
But when I tested some Feral's port of Linux games from Steam, some worked ok on Gnome over Wayland on full screen with Gnome configured to use 4096x2160 while some other games crashed when running on full screen mode (propably something runs of some memory and game fails to handle that without crashing) unless I configure the Gnome's internal resolution lower to 1920x1080.
When I lowered the gnome display resolution from 4096x2160 to lower settings, the wayland implementation of gnome however fails to show on my LG TV. (TV shows just black sceen error from invalid data) but when I login to X11 implementation of Gnome configured to this lower 1920x1080 resolution, Gnome works just fine on with this same TV with this lower resolution. Also the games that Feral's crashed on 4k gnome resolution works now without problem.
Here are the games I tested
1) Feral's F1 2017 works both on Gnome 4k configuration mode with Wayland and lower 1920x1080 mode on X11. I have configured the game resolution in game itself to 1200x720 to get well playable frame rates on my 2400g system.
2) Feral's newer games "Dirt 4" on same setup crashes to sigfault 11 with same setup immediately after going from configuration screen to play if tried on Gnome 4k/wayland mode. Lowering Gnome resolution to 1920x1080 solved the problem on Gnome X11.
3) "life is strange 2" goes little further but will also crash after couple of minutes on Gnome 4k/wayland mode. Lowering Gnome resolution to 1920x1080 solved the problem on Gnome X11.
Another problem I have noticed on Gnome 3.32 wayland implementation compared to X11 is that the display width changes a little bit after display is invoked from the sleep. (about 50-100 pixel lost from width) That problem does not show on X11 gnome display. Maybe these problems are solved on newer gnome 3.34/3.36 but I have had time to test that.
