This stack trace is pretty cursed, with the nested catch_unwind calls.

Bisected to #11660. cc @hymm

Seems to only happen on X11 for me (ran through XWayland), Wayland directly works fine. I am running GNOME Wayland.

[hymm]

I bet it's because we're not waiting for the render thread to finish before cleaning up the window. We probably need to add a drop check that if the render thread isn't on the main thread we should wait for the render world to be sent back before dropping the render world channels.

[hymm]

Could someone test if #11737 helps with this issue?

[Friz64]

Unfortunately, I'm still getting the same issue.

[hymm]

hmm, I wonder if the swap chain is already destroyed when the resource is dropped. Might need to prevent render from being run again if we're exiting the app.

[hymm]

does this branch fix this issue https://github.com/hymm/bevy/tree/no-render-if-app-exit?

The branch gets taken, but it still panics.

[hymm]

weird. 2 possibilities: either the prepare windows is panicking for render run before app exit is sent or it's taking more than 2 ticks for the app to exit, since events only live for 2 frames. Could you add a println! after the 2 if's and see if it logs something after the "exiting early"?

It does not log something.
