Crash on fullscreen with group tab active

Crash fullscreen with group tab active

Hello,
Hyprland crashes whenever I put mpv on fullscreen while having group tab activated.
It works fine if group tab is off. I didn't try with any other apps.

Note: I m starting mpv from terminal (Kitty) with window swallowing.

Thanks for the reproducer.

I repo'd with foot in a debug build:

[tekstryder]

Similar symptom, but no backtrace provided by reporter: #13599

[vaxerski]

I am not feeling well but please check #13614

[tekstryder]

Hope you feel better. Still crashing tho.

STR:

1. create window group with 2 windows, one of them a terminal
2. ensure swallowing enabled for that terminal
3. launch mpv, opening a video, from terminal
4. fullscreen mpv
5. crash

[tekstryder]

Not from a debug build but backtrace should still inform:

Hi @Emeraudia, I can verify this is fixed on git with commit 3b09986.

• Relevant PR: layout/groupTarget: fix crash on null space assignment #13614

Please test and mark this discussion as answered.

Sidebar: currently, with this fix, when grouped, a new grouped window is created for the mpv instance.

I'll open a separate discussion for that and link it here in an edit.

EDIT: See #13637 for followup issue.
