Description Door1 2026-07-01 19:17:02 UTC 
DESCRIPTION
The toolbar action "Show Painting Assistants" doesn't do the action immediately, only doing so when you click/pinch-zoom on the canvas 

STEPS TO REPRODUCE
1. Choose the Assistant tool
2. In Tool Options docker, choose Spline, and add the spline on the canvas
3. Go to Settings, Configure Toolbars, add "Show Painting Assistants" to your toolbar
4. Tap on the "Show Painting Assistants" button on the toolbar

OBSERVED RESULT
The spline doesn't toggle on the canvas immediately. It will only do so once you tap or pinch-zoom on the canvas

EXPECTED RESULT
The spline toggles on the canvas immediately, like it would happen if you did so via the View menu --> Show Painting Assistants.

SOFTWARE/OS VERSIONS
Android 17
Krita 5.3.2.1
arm64
Comment 1 Door1 2026-07-03 21:20:05 UTC 
Additional note:
The Observed Result mentioned above happens when using touch taps (with your finger).

After performing step 4 with a mouse, the spline will only toggle once you hover the mouse cursor over the canvas.

Fix assistant not updating when toggled with an action

Before this commit when the  assistant is being toggled with an action
the canvas doesn't always update immediately, causing it to not be
visible until the canvas is hovered
