ADDITIONAL INFORMATION

Comment 1 Halla Rempt 2021-12-19 13:40:27 UTC

I cannot reproduce this, so...

* Are you using the shortcut override to activate the line tool, or the line tool?
* Does this happen with all brush presets, or only with some
* What is the size of the image you're working on?
* Are you using a mouse or a stylus?

Comment 2 wolthera 2021-12-19 13:41:53 UTC

If this is 5.1+, then maybe it might be related to the speed-sensor changes. I cannot reproduce in 5.0, in any case.

Comment 3 acc4commissions 2021-12-20 03:30:30 UTC

Ok I found out the curprit. It was the airbrush option in the brush. Other brushes without airbrush don't cause the problem with line tool.

Comment 4 tomtomtomreportingin 2022-03-07 21:09:24 UTC

I can confirm this in 5.0.2. All it takes is enabling the Airbrush option, and lines stop appearing after the first line is made.

Additional confirmation: https://krita-artists.org/t/airbrush-modifier-issue-with-line-tool/

This also occurs in 4.4.7, but it does NOT occur in 4.2.5, as this regressive behavior apparently starts occurring in 4.2.6.
