Problem with closing games on PPSSPP core using Gl, Gl core video drivr.

[KamiLordus]

Using the "close content" option on the PPSSPP core freezes retroarch completely. Only killing the process using alt + delete + ctrl helps.
I'm sure it's not a core problem because its latest version PPSSPP doesn't have this problem on retroarch 1.18 cdd6aed. The problem recently appeared about a week/two ago.
I am currently using retroarch 1.18 version 9ab6c62 which already has the above mentioned problem.
For PPSSPP core I use GL video driver, but I tried others like vulkan, gl and it's the same.

edit:
I also tested older versions of PPSSPP from retroarch buildbot such as 1.17 and 1.16 and there is also the same problem.

Windows 11

I can't replicate with current versions of RA and core. Always post logs.

It won't be easy. I only know that retroarch saves the log after closing the game. In this case, retroarch does not save the logo because it freezes completely.

edit:
ok I have something:
retroarch.log

I was able to reproduce on latest master (9ab6c62) using glcore. Also Windows 11. RTX 3060.
I was not able to reproduce using Vulkan.

There's not really anything useful in the logs. I did get these stack traces in the debugger:

Exception thrown (thread labelled as nvoglv64.dll thread):

Although, my behavior does differ slightly from the reported behavior. The application only hangs for a second or two then closes itself. I don't have to Ctrl+Alt+Del it.

I see the same problem with the v1.17.0 and v1.16.0 tags, so it's probably not a RetroArch change.

Tried gl, glcore, vulkan and d3d11, and all close without problems. Didn't try running much longer than successful start though.

[KamiLordus]

After longer tests, I noticed that the problem does not occur with the vulkan driver, the same with dx11. It seems that the problem only appears on GL and GL Core.

It seems that the problem only appears on GL and GL Core.

So you should rename the issue to something Problem when closing games with PPSSPP core using GL or GLCore video driver on Windows ;)

P.S = I can't reproduce the issue on Linux.

I can randomly reproduce on GNU/Linux with gl drivers with audio on, but I can’t reproduce it when the audio is off.

@KamiLordus could you please tested this on your system with audio off or null audio driver?

[KamiLordus]

@viachaslavic I tested the ppsspp core without sound, and with null sound. The tested games close without any problems every time.
Thanks for your suggestions.
Of course, on the GL Core driver with sound turned on, the games still freeze when you try to close them. Nothing has changed here.
