Wayfire crash on xwayland sub-window maximize

[Jelegk]

Wayfire version

0.11.0-3c9a7712 (Jan 18 2026) branch master wlroots-0.19.2 (AUR package)

GPU / Driver

NVIDIA and AMD

Describe the bug

Maximizing any sub-window of an xwayland program with a mouse instantly crashes and exits to tty.
I assume it is for any xwayland program, but I've only confirmed it on REAPER and Krita.

To Reproduce

1. Start an xwayland program.
2. Open a sub-window of the program. (e.g. for REAPER: plugins window, options window, MIDI pianoroll, etc.)
3. Drag and drop the decoration bar of said sub-window on top of the display to initiate a maximize.

Additional context

I have xwayland = lazy in wayfire.ini

The issue does not happen on my AMD laptop, curiously.

I'll be glad to give more output if needed, I'm posting ahead as to not forget

You'd need to compile Wayfire with address sanitizer and post the stacktrace it prints at the end when wayfire crashes, otherwise it is quite difficult to diagnose the issue.

Just tested on an AMD laptop, works fine.
Seems this is a NVIDIA thing

No no, this is a real bug, I am AMD
