you are right, the driver version I wrote was wrong, I first tried 15.40

220.127.116.1194 but the problem is still the same).

As far as I read, this feature is necessary to access the framebuffer
from user mode, right? This is actually the feature I am interested in,
so disabling it won't help me.
Disabling it could still help nail down the problem. If possible,
could you start the VM without any GPU workload from host? If that can
work without problem, the issue should be caused by the GPU switch
between VM and host. if it also meets issues, that may be due to other
config issues. Thanks!
