Trying out the patch I see the following in the "vram" list
VRAM: 1096/2048 vis 195/238 (MiB)
xonotic-glx:( 4364) : 965612 KiB VRAM, 0 KiB
vis VRAM, 5064 KiB GTT
umr:( 4315) : 0 KiB VRAM, 0 KiB
vis VRAM, 0 KiB GTT
gnome-shell:( 3322) : 120548 KiB VRAM, 0 KiB
vis VRAM, 2492 KiB GTT
So you capture the visible ram at the top but not per process. Unless
I'm reading it right some process should have visible ram tallied up right?
