Cintiq cursor offset with drawing tools on Storyboard Pro 22

I’ve recently installed Storyboard Pro 22 while still having Storyboard Pro 20 (which works perfectly) and I’ve got an issue with the pen cursor. What’s most disturbing is that it only happens with the drawing tools : the brush tip and the cursor pointer do not match anymore, whereas with other tools and in all other windows it’s perfectly aligned.

It also only happens with my Cintiq pen, not with the mouse cursor:

Thanks in advance for your help!
