SUMMARY
Same bug from :
https://bugs.kde.org/show_bug.cgi?id=515639
But not fixed yet in Krita 5.3.1

STEPS TO REPRODUCE
1. create a rectangular vector shape
2. using one of the edge's anchor and the vector shape, try to click and drag an edge
3. without stopping the drag, release your click 
4. look at what happens with the movement of the cursor

OBSERVED RESULT
The vector shape stays glued as if you didn't release the drag, 
and will stop only if your cursor movement is still.

EXPECTED RESULT
Right after releasing the click, the vector shape should instantly commit
and the position at which the cursor was when the click has been released.
No glue-ing of the vector shape to your moving cursor position should
happen after releasing the click

SOFTWARE/OS VERSIONS
Windows 10 Pro

ADDITIONAL INFORMATION
Tested with a Huion H1061P tablet
