Hey!

I had a similar issue on a fresh setup with NVidia drivers from backports.
After resume fonts disappeared and graphic/rendering was 'unstable'. I
added 'NVreg_RegisterForACPIEvents=1' to the NVidia kernel modules' options
and all the issues were gone. Maybe this helps?

In /etc/modprobe.d/nvidia-kernel-common.conf:
- options nvidia NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=44 NVreg_DeviceFileMode=0660
+ options nvidia NVreg_DeviceFileUID=0 NVreg_DeviceFileGID=44 NVreg_DeviceFileMode=0660 NVreg_RegisterForACPIEvents=1 NVreg_EnableMSI=1
