Poor Blender performance after a few minutes of use


When starting the VM, Blender works perfectly. After a few minutes of use (5 to 10 min) performance becomes very low (2 fps).
I don’t have this problem with driver version 430.46. The problem appeared with later versions.
here is the configuration of the vm:
Debian 11. (I tried with debian 10, the problem also exists)
Driver Version: 495.46 - CUDA Version: 11.5
Blender: 2.92 (the problem exists with 2.78 too)

performance test with __GL_SYNC_TO_VBLANK=0 glxgears shows constant FPS of 1177.705 FPS


I attach the bug report with and without the bad performance.
