I gave Hyprland a try some weeks/months ago, and seemingly it had a video memory leak where after some hours of usage, it ended up taking more than 5GB of VRAM, with no signs of slowing down.

I found one issue (https://github.com/hyprwm/Hyprland/issues/2945) mentioning something similar, but no resolutions as of yet, so not sure what's going on.

Gnome3 doesn't manifest the same issue, so worth checking out if it happens to you if you're curious about moving from Gnome to Hyprland.
