Description omiya 2014-07-27 12:42:05 UTC

Krita stops responding when layer opacity is changed while a filter preview is enabled.
I confirmed it in the following filters so far: Dodge, Levels, Color Adjustment Curves, Gaussian Blur and Pixelize.

Steps to reproduce:
  1. Prepare an image to apply a filter to.
  2. Open a filter dialog.
  3. Check the 'Preview' checkbox in the dialog.
  4. Change layer opacity via the Layers docker while the preview is shown.

I have found this is probably a duplicate of https://bugs.kde.org/show_bug.cgi?id=334982 .

Yes the bug is fixed in master, but we should backport the fix to 2.8
