Issues with gnome 47 on nvidia drivers

Help
1

Hello! I am trying to configure nvidia drivers to work with gnome 47. I am using fractional scaling(experimental feature) through dconf(with extraGSettingsOverrides). The scaling is set to 125%. After a little bit of resizing(or sometimes after launch) the app freezes, and then the visual corruption occurs. The issue applies only for gtk4 apps(other aren’t affected). Also on the scaling 100% or 150% the issue is gone. I am getting this error message in the terminal (debug output of the app):

(epiphany:15726): Gtk-WARNING **: 19:19:54.362: Unknown key gtk-modules in /home/paul/.config/gtk-4.0/settings.ini

(epiphany:15726): Gsk-WARNING **: 19:20:09.899: vkQueueSubmit(): The logical or physical device has been lost. (VK_ERROR_DEVICE_LOST) (-4)

(epiphany:15726): Gsk-WARNING **: 19:20:15.043: vkQueueSubmit(): The logical or physical device has been lost. (VK_ERROR_DEVICE_LOST) (-4)

I am using Nvidia Open Stable drivers(550). Changing drivers version(latest. production, beta) didn’t help.

My NixOS configuration:

Look in - hardware-configuration.nix, there you have it: boot.kernelModules = [ “kvm-amd” ];

Removing it didn’t help. Tried booting into arch and had the same problem, so i think it is gtk4/nvidia specific issue not depending on system.

Found this issue on gnome gitlab:

It’s gsk vulkan bug, so i will switch to Plasma for now
