Short description of error
When weight painting GP strokes blender sometimes crashes when I smooth weights, also deleting Vertex groups doesn't work as expected

Exact steps for others to reproduce the error

Blender crashes often, when I try to smooth GP stroke weights. I tried to reproduce the crash but couldn't find a definitive way to do so from scratch. So I'll attach a blend file, that can be reliably crashed.
While I was bug hunting I also discovered some other weird stuff, that might be related.

  • crash: select face, add weights, smooth weights -> crash
  • vertex groups: select 1,2,3 object, delete VG named 1, after that VG 2 will be empty, VG 3 is now what was VG 2 before
  • black points: select squiggle, smooth weights and increase the iterations in the adjustment popup, at some point some points will change from colored to black and cannot be weighted anymore

I have fixed the Smooth bug, but you have added several bugs in the same report.

Please, include only one bug by task.

oh that's great to hear. Yeah I wasn't sure, if I should split it or not. shall I create new tasks?

Yes, create separated task always for each bug.

I'm looking now at the delete group bug.

I'm going to close this task because firt bug is fixed. Next bugs were separated in different tasks.
