Hey, this is one of the weirdest and most annoying errors with 4.8 ue4. I notice that i will sometimes try to open up an editor window, and suddenly the window dissapears, and cannot be viewed. The only way to view it is by doing ALT+Tab and that just shoes up a a white window as shown below.
Anyone else having this error, or ever ran into it? It can last for a few days, and then it just randomly starts working again.
