Crash in wlr_render_rect (assertion failed)

[russelltg]

Please fill out the following:

• Sway Version:

  • 1.7 (packaged by Arch)

• Debug Log:

  • I haven't been able to reproduce it reliably, I'll add a log if I find a way to repro easily.

• Configuration File:

  • My config: https://gist.github.com/russelltg/fc021d4dcd9a7c01c552758bcefc1407
  • Again, if I find a reliable way to reproduce the issue I'll try with the default config

• Stack Trace:

• Description:
  I'm not 100% sure exactly what causes it. I think it may be related to resizing windows.

I assume a core dump would not be that helpful considering you'd need my binaries as well, but I've saved it locally so am happy to answer questions about it.

[emersion]

(gdb) p ob_bg_height
$30 = 0

This sounds like the cause of the issue. What is config->font_height set to?

(gdb) p config->font_height

Similar-looking issue here.

I was running cadence over xpra with a fullscreen window, which I suddenly couldn't un-fulscreen). As it happens, under some cadence windows, shortcuts that use meta are not recognized (which is annoying). Fearing for this, I started panicking and sending a stream of commands to make it floating, resize it, unfulscreen, to no avail. Until I tried selecting the hidden floating window (possibly modal) and closing it. The active window was just a vertical bar, a floating <1px wide window. I tried resizing and/or making it tiled again; that's when the crash hapened.
