• Description:

  • The steps you took in plain English to reproduce the problem.

The file manager I use [Caja] exhibits odd behaviour, and the devs wanted me to see if it did so with windows that were floating, as well as tiled.
I wished to have it in exactly the same position as when tiled, so I tried to position/size it with percentages. This failed, for some reason.
I switched to using pixels, with the exact position/size as the tiled version (right half of a tiled 4K monitor, the other half being my text editor [featherpad]).
I goofed up, and wrote 'pt' instead of 'px' for the positioning/sizing units.
This causes Sway to crash (!). [Dumped back at the login-manager [SDDM]]
After I booted with a live-usb and edited the for_window to remove all floating/position/size aspects, and rebooted, all was well.

I copied my usual config out of the way, and altered the standard 1.9 config minimally to use the bum for_window, and launch caja as usual,
I logged out/in, and Sway still crashed.

Odd, that such a minor syntax error could crash Sway...!

Odd, that when handling "width" it would ERROR using the word "height"

IMMEDIATELY after this, Sway crashes:
