On the new presets stack, two of the smudge presets will set themselves as modified (on preset icon) with out been modified at all. Steps to reproduce: -Open Krita/New document -Select either of the Blender_textured or Blender_textured_marble and do some strokes with them After some strokes the icon will show the modified status when there hasn't been any real change made on the preset. On IRC Wolthera has mentioned to be a the setting of a texture offset problem.
Can you verify if this is still happening on the 4.0 stable? I did a fix a little while ago that fixed a bunch of situations where the brush became modified on accident. For reproducing this on master, I tried to switch to the "k) Blender Textured Soft" brush and made some strokes. It doesn't appear to be getting marked as modified when I make some strokes.
This bug has had its resolution changed, but accidentally has been left in NEEDSINFO status. I am thus closing this bug and setting the status as RESOLVED to reflect the resolution change.
