Game runs, but the screen is black unless fast forward is used, when using d3d11

[Denshadego]

As the title says. Game starts, you can hear the sound and manouver through menus if you know them from memory, but the screen remains black, unless you push the fast forward button. This only happens with d3d11, which is a shame, because is the one that runs best for me, sans the black screen issue.

Tried with a clean retroarch installation, using no shaders and various combinations of vsync options, with no luck.

I'm aware of the issue that you have filed, it has been around for a long time.

Here is a a temporary workaround that worked for me in GNU/Linux:

1. Navigate to Main Menu -> Drivers
2. Click on Video
3. Change the value from gl to glcore
4. Close RetroArch
5. Start Retroarch
6. Run step 1-2 to verify that it is set to glcore
7. Open a PS2 game, and have fun!

For the devs, no idea if it helps but here's the errors I'm getting with the D3D11 debug layer enabled:
