I have experienced some crashes when opening clients (seems to happen more often if firefox is open). sadly 4 out of 5 times i was sending errors to /dev/null (that's not very helpful) but i recorded the last one, here it is:
dwl: types/xdg_shell/wlr_xdg_surface.c:15: wlr_xdg_surface_from_wlr_surface: Assertion `wlr_surface_is_xdg_surface(surface)' failed. thread 'thread 'mainmain' panicked at '' panicked at 'failed to read wayland events: Broken pipe (os error 32)failed to read wayland events: Broken pipe (os error 32)', ', <::std::macros::panic macros><::std::macros::panic macros>::55:6 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace thread ':main6 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace ' panicked at 'failed to read wayland events: Broken pipe (os error 32)', <::std::macros::panic macros>:5:6 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace thread 'main' panicked at 'failed to read wayland events: Broken pipe (os error 32)', <::std::macros::panic macros>:5:6 note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

I will run it with RUST_BACKTRACE enabled as suggested, is there anything else I should provide?
This is on arch linux, wlroots version 0.10.1-1 and wayland-protocols version 1.20-1
