 There is also a known memory leak when running the renderer on Linux - however, it is uncertain currently whether this is an issue with Proton or there is something else at play - see https://github.com/Yellow-Dog-Man/Resonite-Issues/issues/5246.
 
-### OpenComposite
+### Crash on launching in VR mode
 
 Currently, OpenComposite is known to crash Resonite when used in VR, so attempting to use OpenComposite for Resonite is not recommended.
 
+Symptoms:
+- Crashes only in VR mode, where after several seconds a black window appears and closes briefly, then Resonite stops within approximately 30 seconds.
+- The normal log file shows a renderer crash: `RendererProcess has exited. Shutting down.`. There's a Player.log file.
+
 See https://github.com/Yellow-Dog-Man/Resonite-Issues/issues/5152 for more information.
 
+### Crash on launching in desktop & VR mode
+
+Proton data can get corrupted, which will result in consistent crashes on launch. This only applies if you've already replaced OpenComposite (see above).
+
+The symptoms are:
+- Crashes 2 seconds from launch in desktop mode (and in VR)
+- No log files (no main log, no Player.log, no crash log, no proton log with PROTON_LOG=1, only the boostrapper log)
+- It may be accompanied by error windows if you're using a mod loader.
+
+Navigate to compatdata in the folder above Resonite's folder (by default `.local/share/Steam/steamapps/compatdata/`) and delete the `2519830` folder; it will regenerate on the next launch. Then verify the integrity of Resonite files in Steam (right-click Resonite and go to Properties>Installed Files>Verify).
+
+It may be enough to just verify file integrity in some cases.

 ### Crash on loading into a world with video players
 
 On GE-Proton9-10 (for example), loading into a world with e.g. a YouTube video or live stream can crash the game. Try using the latest GE-Proton-RTSP release.
