SUMMARY When the drawing angle is locked, the drawing angle of the pen tip will still change for a period of time after the brush contacts the canvas, and then the final drawing angle will be maintained, which will lead to the confusion of strokes during rapid drawing EXPECTED RESULT After the pen tip touches the canvas, the drawing angle should not change SOFTWARE/OS VERSIONS Windows: Windows11
What do you mean by 'When the drawing angle is locked'? Using brush rotation controlled by drawing angle (and a suitable/obvious brush tip) I find that if I use the Line tool or snap to an assistant then the drawing angle does not have any start of stroke glitches. If I use the Freehand Brush tool then the start of the line does often show a start of stroke glitch on the drawing angle, which is not surprising.
Yes, I mean to use the drawing angle to control the rotation and check the lock However, after the start of the line, the drawing angle may change many times, instead of taking the angle after the first change as the final drawing angle. I compared Photoshop, the drawing angle will only change once
I guess Photoshop may take the first nib stamp as the final drawing angle, and Kriat may be a period of time after the beginning of drawing
Ah, that 'Lock'. I can confirm this for the 4.4.7, 4.4.8 and the Nov 10 5.1.0-prealpha (git 17a3a4c) appimages on Debian 10. When Lock is enabled, there is often a glitch in the brush tip angle while a stroke is being made. I attach Rotation Lock Bug.png as an example of this.

Yes, my test results are the same
