Hi @victorr2007 ,
Was this bug report collected after setting NVreg_PreserveVideoMemoryAllocations=1? Your logs show that it wasn’t applied.
I see corruption on desktop after resuming from suspend when NVreg_PreserveVideoMemoryAllocations is not set. There are no issues with NVreg_PreserveVideoMemoryAllocations=1. Please retest and verify that it gets applied. Please run the following command to verify :-
# cat /proc/driver/nvidia/params | grep PreserveVideoMemoryAllocations
Thank you
