I have a fresh install of Ubuntu 19.04 and I've noticed that my background and/or lockscreen background goes either black or very colourful crazy after returning from suspend. Any ideas why does it occur?
Sometimes desktop background goes fine after changing the background image but once I go suspend and return again, it goes either black or colourful.
I have GeForce GTX 1060/PCIe/SSE2 on Asus FX502V laptop. I'm using nvidia-driver-418 tested proprietary driver.
