>From my side, it should be like:
VRAM: 249/4096 vis 50/237 (MiB)
steam:( 3203) : 63304 KiB VRAM, 14088 KiB vis VRAM, 20072 KiB GTT
compiz:( 2510) : 82144 KiB VRAM, 7072 KiB vis VRAM, 20460 KiB GTT
Xorg:( 1682) : 125536 KiB VRAM, 11616 KiB vis VRAM, 21812 KiB GTT
What's the value of visible_vram_size on your side?

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?
