SUMMARY
***
At least on Nvidia, there seems to be some vram leak in kwin_wayland, it always
increases and never goes back to how it booted. Keeps on consuming a lot of
VRAM
***
STEPS TO REPRODUCE
1. Open wayland session, browse the web, then resize a few windows(best to be
xwayland ones), close them out reopen them, resize again, the vram on
kwin_wayland will keep on increasing with never dropping back to it's original
usage.
OBSERVED RESULT
Kwin_wayland keeps on consuming a lot of VRAM
EXPECTED RESULT
to remain the same one as boot +/-, not increase with 300-400mb and keep on
increasing to take more than 1GB
