I am running F31 in a vm under Windows 10, and when I use Gnome under Wayland with the screen in the equivalent of 3840x2160 I get double overlays in windows when expanded past a certain size, which was initially highlighted when I ran with windows maximized to 3840x2160, but this issue did not occur in Gnome running on X, and did not occur in KDE. Just one further question, are you able to increase the refresh rate and see if that makes a difference? I run my system in 3840x2160@60 mode when running X (Wayland scaled, X didn't) by adding a file into /etc/X11/xorg.conf.d specifying the relevant modeline to run X in that mode. regards, Steve
