I'm trying the new, wonderful, liquify tool. Unfortunately, it's quite crashy for me.

Steps to reproduce :

  • Open an image, liquify module, point tool -> add a point.
  • Move the spot controlling the radius several times.
    => it crashes randomly but often for me (about 1 out of 5 or 10 moves).

Backtraces attached. Let me know if I can add more information.

Using dt version c1ba149 (Merge pull request #1153 from AlicVB/coll_pathsort, 2016-03-02). Debian 8.3.

Indeed! I can reproduce very easily, this was not a problem some time ago as I have used quite a lot this module. Probably a recent regression. Investigating.

#2 Updated by Pascal Obry over 4 years ago

I expect the crash is fixed now.

Wow, that was quick!

I'll check that tonight. I'll reopen if needed.

Merci :-)

I had still a crash in some cases. Should now be fixed so please be sure to test with: 64c70a8.

The crash I experienced earlier is indeed gone. And actually I had a lot of mis-behavior that are gone too. That tool is really cool!

I could get one more crash by zooming out (zoom = small) and make an insanely large point (the diameter was bigger than the picture). Backtrace attached (but this doesn't seem reproducible).

I could get another one with zoom = small and the "draw lines" tool by drawing a line far away from the picture, around the picture. Backtrace attached too. This one seems reproducible.

(it seems I don't have permission to reopen a closed bug, or at least I can't find how to do it)

Just so that the "new" crashes do not get lost, I created a separate bug for them: #10945
