@Crates Jeez! :) I thought I had a problem with part of my screen.

@GeopJr forgot to mention this is happening on multiple apps. Not sure what I am supposed to run with that parameter.

@Crates by default GTK apps use Vulkan for rendering and some drivers and graphic cards have some issues. That env var changes the renderer. Run an app that has these artifacts with it to see if it fixes them and if it does, set it on startup so all apps use that renderer.

@GeopJr I did
`export GSK_RENDERER=ngl`
and then ran the Tuba flatpak. No change.
Did I do it wrong? (sorry for my n00bness)

@Crates try running it with GSK_RENDERER=ngl flatpak run dev.geopjr.Tuba if there are still artifacts, try Vulkan instead of ngl

@GeopJr you are amazing! I added it as a variable in flatseal and now it’s all looking normal!!! Thanks a lot!

@Crates @GeopJr Further you can add `GSK_RENDERER=ngl` as a line in `/etc/environment` so it applies to all of your apps.
