SUMMARY
***
The title is basically the summary.
***


STEPS TO REPRODUCE
1. Go to Settings, Configure Toolbar, and add enough actions to mainToolbar so that they can't all fit into the toolbar
2. Go to Settings, Configure Krita, Canvas-only settings, have everything checked except toolbars and dockers
3. Start a new drawing
4. Activate canvas-only mode (in my case, I used the finger-tap touch shortcut)
5. Click the expand button on the right edge of the toolbar to show all of your hidden actions
6. Disable canvas-only mode with the finger-tap shortcut

OBSERVED RESULT
Krita will immediately crash.

EXPECTED RESULT
To disable canvas-only mode and not crash.

SOFTWARE/OS VERSIONS
Android 13, Motorola near-stock UI
Krita 5.1.5, arm64 apk

Hi, AppTest!

Thank you for the report! Could you please test Krita 5.2.0 RC1 version of Krita? We fixed a lot of canvas-only-mode-related bugs in it...

I tested it there too, and it also crashes in 5.2 rc1. It can be reproduced following the same steps I indicated above.
Comment 4 Bug Janitor Service 2023-10-03 03:46:23 UTC 
Thanks for your comment!

Automatically switching the status of this bug to REPORTED so that the KDE team
knows that the bug is ready to get confirmed.

In the future you may also do this yourself when providing needed information.
Comment 5 Halla Rempt 2024-10-29 13:16:13 UTC 
I suspect it's actually a bug in the qwidget module on Android, since it is android-specific.
Comment 6 Reinold Rojas 2024-11-12 04:14:07 UTC 
I can reproduce this as well so setting to confirmed. Recreated on latest from play store 5.2.6.

Also noting that the crash is very dependent on it being a new file. If you draw a tiny bit before following the reproduce steps Krita will not crash.
