Description zeroreindra22 2025-11-23 04:35:30 UTC

SUMMARY
Krita brush cursor freezes on it's last position after many strokes. 

STEPS TO REPRODUCE
1. Set up a non-display drawing tablet via bluetooth to the phone. 
2. Open/Make a new project on Krita. 
3. Alternate between making brush strokes with the drawing pen, drag and zoom using the touchscreen, and clicking anything in Krita's tabs/windows (selecting brush presets, layers, etc). 

OBSERVED RESULT
After some time letting go of the brush will freeze the cursor on it's last position within the canvas until another stroke is made and so the cycle goes, making drawing virtually undoable.

EXPECTED RESULT
No freezing whatsoever. 

SOFTWARE/OS VERSIONS
Android: 15

ADDITIONAL INFORMATION
I draw on a Galaxy Z Fold 3 using Wacom Intuos CTL-4100WL via bluetooth.

This has also been reported to me as happening with a Huion Inspiroy Frego M, along with a video of it: https://files.catbox.moe/c75u0i.mp4

Since there's two corroborating reports, I'll set this to confirmed, but I haven't actually managed to make this happen myself.
