Description
After updating an egui + burn app to wgpu master, I observed random crashes with a generic "validation failed: parent device lost" error. Nothing in particular seems to cause the crash, even just drawing the app while firing off empty submit() calls seemed to crash.
After a bisection it seems to come down to this specific commit: ce9c9b7
It doesn't look that suspicious but does touch some raw pointers so idk... I definitely can't tell what's wrong anyway.
I can try to work on a smaller repro than "draw an egui app while another thread fires off submit()" but maybe this already gives enough hints.
Thanks for having a look!
