RetroArch crashes when Saving States with Sync to Exact Content Framerate Enabled #10576

Open protopizza opened 4 years ago

protopizza commented 4 years ago

First and foremost consider this:

Description

I have under video synchronization options "Sync to Exact Content Framerate Enabled" set to ON. I have neither G-Sync nor FreeSync enabled (someone suggested I enable this option to try to fix netplay rollback issues). When I try to save state with Savestate Thumbnails ON, RetroArch crashes. The savestate still gets created, RetroArch just crashes with no warning. This only crashes if there is an existing savestate in the slot.

This might be related to #10521, but they were primarily discussing widgets, and enabling/disabling widgets had no effect here.

Expected behavior

RetroArch doesn't crash in the above scenario. If a screenshot thumbnail is unable to be taken, display an error, but don't crash. It took me some time to realize the cause of this behavior.

Actual behavior

RetroArch crashes.

Steps to reproduce the bug

  1. Already have a savestate in slot.
  2. Set Video->Synchronization->Sync to Exact Content Framerate Enabled to ON. (G-Sync/FreeSync not supported)
  3. Set Saving->Savestate Thumbnails to ON.
  4. Load content.
  5. Go to quick menu, and save state.
  6. RetroArch crashes, though the savestate is still made.

Bisect Results

This seems almost certainly due to "Sync to Exact Content Framerate Enabled" causing screenshots to fail, which in turn causes RetroArch to crash. I'm using the 1.8.5 stable build currently.

Environment information

snaphat commented 4 years ago

I can confirm this is still an issue with 1.8.9 stable. It only occurs with the vulkan driver enabled (GL works fine for example). As the OP said, It definitely doesn't matter if freesync/gsync is enabled in the video driver settings (newest stable Nvidia driver in my case, but the issue showed up with the prior driver as well).

It specifically has to do with having the vrr_runloop_enable setting enabled (which is enabled via the "Sync to Exact Content Framerate Enabled" setting in the GUI).

I was able to reproduce the crashes on nestopia, fceumm, and snes9x cores, but not with genesis_plus_gx and vba_next. So it's only certain cores that cause crashes.
