Closed Jcw87 closed 1 year ago

Fixes the primary issues in #379

Jcw87 commented 1 year ago

Also added a fix for the game switching graphical bugs that only seemed to afflict ParaLLEl.

Jamiras commented 1 year ago

I've verified these changes fix the issues I mentioned in #379

  1. Mupen64plus-Next > Mupen64plus-Next : seems fine
  2. Mupen64plus-Next > ParaLLEl : rendering issues, video failure on screenshot
  3. ParaLLEl -> Mupen64plus-Next : seems fine
  4. ParaLLEl -> ParaLLEl : rendering issues, video failure on screenshot.

I was able to successfully take a screenshot after each of these paths. Thanks!

However, if I switch from ParaLLEl to ParaLLEl or Mupen64plus-Next (bullets 3 and 4) just after Mario's face appears, it crashes. The stacktrace is entirely in parallel_n64_libretro.dll, which suggests stack corruption. I don't think it's related to the GL context stuff, but if you wouldn't mind taking a look, I'd appreciate it.

EDIT: duplicated the crash in RetroArch using similar steps of Close Content just after the face appears and quickly reloading from history.

Does that crash occur if both of my PRs are merged? The other one fixes a crash when shutting down ParaLLEl and attempting to start any core.

It does not. I did not realize there were two PRs. Thanks.

I wonder if there's a similar unflushed error causing RetroArch to crash.
