Is my editor text eating itself?

Hello everyone,

Sorry if I’ve posted in the wrong section, I was just wondering if anyone had experienced an issue with the editor text before (as pictured).

Parts of the texts pixels are missing…like its eating itself!

It can be anywhere, any window or toolbar…no text appears to be safe!

I am still investigating as there appears to be some other weird issues that have come out of nowhere, such as when I play in editor some actors vanish, materials seem to change colour and then some weird lines appear that seem to move randomly very fast…

didn’t know if anyone had seen/had the same?
