Step to reproduce:
1. Install driver
./NVIDIA-Linux-x86_64-535.183.01.run --dkms --glvnd-egl-config-path /usr/share/glvnd/egl_vendor.d
2. Reboot.
3. Open VM over RDP or SPICE.
4. Open site like webgl test.
5. Got artifacts or black screen.
On Intel driver all works fine.
When i got artifacts on host logs appeared error:
