DX11 + Win10 Pro + Full Screen = Black Screen

[barat]

Hello,

I upgraded my 3570k to 4790k and reinstalled Windows 10. Before upgrade I had Win 10 Home, and now I bought Win 10 Pro (shouldn't be a case IMO).

Before format Dolphin was working correctly, but now when there is option "Use Fullscreen" checked under graphic->general I see only black screen after game start. Clicking mouse button will make dolphin crash ...

Weird thing is that on official 5.0 release it's working fine. Newest Ishiiruka starts a game as well. I can't run it fullscreen in new dev builds ...
Problem is on DX11, because if I chose DX12 or OpenGL backends - game starts fine.
Additionally - when I uncheck "Use Fullscreen" and start game in newest dev builds - game starts. I can then press "ALT+ENTER" and I have fullscreen ...

Someone knows what's going on?

EDIT:
Checking "Render to Main Window" under graphic->general fixes the issue ... but previously it was working OOTB ("Render to main..." isn't default checked option)

Sounds like the regression from 5.0-76, which is a known issue. You've already figured out how to avoid it, so I don't think I have anything more to say.

Ok - good that it's known and will be (?) fixed someday. For me it's not a problem if game needs to render to main window if it doesn't affect the performance - I'm starting all games from Steam
