when using the deform-brush on Lineart with transparent parts it only deforms the RGB-Data not the Alpha. The result is a blotch instead of a deformed line. Reproducible: Always Steps to Reproduce: 1. have some lines on transparent BG 2. Deform it with the deform-brush engine (doesn't matter which mode) 3. Result is not what expected

Hm, the deform brush has always behaved like this, so I'm not sure it's a bug or the way Lukas designed the brush engine... The behaviour you're after is implemented in the liquify option of the transform tool.
Hi, I hope that its not the case, that it behave like this. And I really dont think so. why should this tool behave compleately different on transparent background than on opaque? And the reason why I am using this Brush is very fast to use. ?and maybe more performant? In my case its fine when the image quality suffer from using the deformbrush, because mostly I use it in an early scetching state.
Well, we might change it, but tbh, before we find a volunteer for hacking that code could take a longish time. Since this brush has always behaved like this, changing the behavior makes it a wish, not a bug.
This is what happens when you set the blending mode to 'normal'. If you use 'copy'(which the only default preset, 'move_tool' is set as), it works as expected.
Ah, thanks! Then we can just close it.
Ok then. Thank you very much for the hint and sorry for the disturb. Great software!
