Description

vram leak (?) on nvidia when resizing some windows, e.g. firefox requires nvidia_anti_flicker = false It does seem to stop at a certain amount though Maybe related to #4294

How to reproduce

1. Have an nvidia GPU
2. Set OpenGL:nvidia_anti_flicker = false
3. In an empty workspace, open kitty and firefox next to each other. Drag to resize them, and vram goes through the roof

Crash reports, logs, images, videos

No response

if it stops, it might be nvidia just queueing frees but not actually conducting them right away

[thejch]

Yeah it stops but it's after it reaches 1.5 or 2 GB for me so still very bad. Nothing can be done on hyprland side? Also when it stops it doesn't come back down. It just stays at that amount.

[vaxerski]

No clue, I've never seen this happen on AMD, so it could also be an nvidia bug.

I can't reproduce it on nvidia

I wonder if it's related to the issue I'm seeing here (although it's xwayland and not firefox)

This seems somehow mostly gone now, probably due to some of the recent rewrites. Now although it does still happen sometimes, it never lasts very long before the vram goes back down so it doesn't really concern me anymore. I'm just gonna close this for now.
