Hi @pcaggegi , in 3.4.0 it is set to round with the button. (I think that was also the default in 2.81a although the control is in a different place.)
I’m using strength 1.0, fixed radius, with tablet controls all disabled. (I have a tablet but often use the mouse.)
The line ends appear as round while extrusion is being done.
If I then scrub/step back and forth in the timeline, (while the duplicated stroke points exist), the ends appear square/angled for all keyframes except the last.
When each hidden duplicate stroke point is dissolved, the affected end then correctly appears as round.
After all the duplicated stroke points have been dissolved, scrubbing back and forth displays the ends properly as round at every keyframe.
Hopefully this clarifies things. It’s a little hard to explain without a video.
