I was greeted with this problem upon launching Wow today.
The screen is Black! I have narrowed it down that it only happens in Fullscreen mode. The game will run in Windowed mode.
I want to play in Fullscreen, some things I tried but did not resolve the issue: Deleteing wtf, cache, interface folders did not help, Changing to directx11 did not help, uninstall discord did not help, scan and repair did not help. GPU drivers are up to date 6700xt.
