nixos/gnome: Gnome 49 App Rendering Issues #464152
Description
Nixpkgs version
- Unstable (25.11)
Describe the bug
After a recent update on 25.11 Unstable, a lot of my GTK/Gnome apps are having weird rendering artifacts and animation issues. I wasn't sure if this was a Gnome or a GTK issue, or a NixOS issue at all, but I can't find a similar bug reports in other projects so I thought I would try here. I only see the issue in what seems to be GTK apps and it only started over the last day or two with updating to latest Gnome 49. I am using the Intel Xe drivers.
Opening an app such as Mission Center will display animations incorrectly, will often have symbols and boxes instead of text, and seems to have artifacts appearing and disappearing. Nautilus shows the same behaviour, with the entire window flashing and strange squares appearing around its borders. This is also present in the screenshot preview app that is default in Gnome, with the borders of the window flashing and a purple box appearing at random around the edges. It seems to be in a lot of GTK apps. This was not present before the last couple of days, and I have been keeping 25.11 up to date pretty regularly.
Steps to reproduce
Be on Gnome 49 and Nixos 25.11 Unstable. Open a GTK app. The app will have animation issues, flashing, symbols and boxes.
Expected behaviour
There should be no animation issues, flashing, and symbols/boxes instead of text in GTK apps.
