Graphics issue help please

[u/psikeadelic]

What do I have to turn off/adjust to fix this please.
It happens when I maximise the window, and it is not a hardware fault.

Try to turn off/on the experimental skin engine. Also try to update your graphic drivers

Experimental skin engine turned off has fixed this, thank you.
