Only on this core, sometimes when I stop fast forwarding it hangs on the last fast forward frame indefinitely, but you can still hear the game running in the background, at that point I need to force restart the emulator as I can't even use the RetroArch menu either.

Clip of this happening, 15 seconds in:

Is this known? Can I get around it somehow?

Thanks! Looking at the latest comments I already had fast forward frame skipping off and frame duping on in that clip...

#

I am going to try not using vulkan instead

#

Uh and I am not on IOS or Linux, but on Windows 11

It affects all platforms

#

I think the gl renderer is not fully functional

Ah

#

Was hoping I could just switch to open gl, guessing I need to pick my poison here?
