Operating system: MacOS Mojave 10.14.6
Graphics card: Intel HD Graphics 6000 1536 MB
2.8 rendered view
Short description of error
I'm getting a usually green/black but occasionally with hints of red and pinkish screen, whenever I change something in rendered view. The view also will occasionally start layering the old image on top when I move the view.
Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).
I don't know, it just sort of happens when I open rendered view. (eevee and cycles engines)
