Description

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.

Research direction

Start by reproducing the black screen with d3d11 on the listed Windows 10 and Radeon hardware, then inspect the attached retroarch log while comparing normal playback with fast forward. Trace the d3d11 rendering path implicated by the reproduction. Done means the game displays normally without requiring fast forward, while other reported behavior remains intact.
