Black screen on full screen issue (updated)

okay so after not receiving any input after about 6 hours and blizzard not allowing me to make another post on the same thread updating the issue for some reason, I’ve decided to make another post on the subject I spoke of in THIS thread. upon looking into the issue further, I found out that for some reason the issue only persists on fullscreen, and though it does work on windowed mode it is incredibly slow.

as said previously, I have no idea why its doing this as nothing has changed really about my computer, and it use to work perfectly fine. If I could get help with this issue it would be greatly appreciated.

Closing this thread as we already have one open.
