Description vurentjie 2026-02-10 22:14:30 UTC 
SUMMARY
The Cockpit and Dual screen window layouts are not compatible with Krita 6. I don't actually use these but I happened to try them today and noticed the issue.

STEPS TO REPRODUCE
1.  Open Krita 6
2.  Open or create a new document
3.  From the workspace switcher, select either one of the window layouts: "Cockpit (laptop mode)" or "Dual screen editing"

OBSERVED RESULT
Krita crashes with a seg fault. I think this might be an issue with the .kwl files compatibility. 

EXPECTED RESULT
Doesn't crash.

ADDITIONAL INFORMATION
Comment 1 Freya Lupen 2026-02-11 15:58:24 UTC 
Confirmed, selecting a window layout crashes on Qt6 but not Qt5.

It crashes here
> 0   libkritaresourcewidgets.21.0.0.dylib	       0x103dbc2e0 KisResourceItemChooser::activate(QModelIndex const&) + 336 (KisResourceItemChooser.cpp:515)

When the window layout is activated, the updates are blocked on the window layout chooser, it emits the resourceSelected signal, a bunch of other stuff happens,  and then eventually it unblocks the updates.
However, by the time it gets back to `d->updatesBlocked = false;`, `d` is null for some reason, so it crashes instead.
