Graphics glitch when I open studio?

Not sure why, it’s been happening for a little while. I’ll be building in studio then put my PC to sleep when I go to work, when I get back on usually the studio map looks very staticy or black blobbed… anyone know what the issue may be?

Restart studio.

EDIT: lol ↓

Unplug and replug your computer

Turn of the mains electricity and turn it back on.

Turn off the national electricity grid and back on again.

Reboot your graphics card driver.
