anv: dEQP-VK.graphicsfuzz.spv-stable-maze-flatten-copy-composite fails
This is because the generated shader seems very heavy to consume. I can workaround this by setting a big value for /sys/class/drm/card0/engine/rcs0/preempt_timeout_ms (like has to be done with UE4 editor, blender etc) but ideally this should not have to be done.
