[nvidia] Xorg process loads CPU heavily after resuming suspended laptop HP Probook 470 G4

[Beowulf]

The issue is triggered by waking my notebook up after suspending. After that CPU is loaded heavily, and I have to re-boot. The computer does not shut down properly and I have to press the button to turn it off.
After re-booting I do not have this issue until I suspend my notebook again.
