Bug ID: 445691
Summary: Alpha Mask not working properly with predefined brush
tips
Product: krita
Version: nightly build (please specify the git hash!)
Platform: Microsoft Windows

Status: REPORTED
Severity: grave

Brush editor showing the difference between the two brush tips
The brush mode option "Alpha Mask" for predefined brushes doesn't seem to work
properly. When it's selected, the brush tip is somewhat transparent although
the brush tip is black and opacity is at 100%. The problem seems to occur when
the brush tip is a transparent PNG file. I had them exported from abrmate. When
the brush tip isn't transparent (black on white background), the problem
doesn't occur. It's also fine if "Color Image" is selected as brush mode.
This also affects the brush tip in the Masked Brush category, as the default
(and only ) option is "Alpha Mask".
I've checked the issue in Krita 4 and there everything works as expected.
Attached is a screenshot of the brush editor showing the issue. The top brush
dot in the Scratchpad is created with "Alpha Mask" selected, the bottom one
with "Color Image" selected.
I hope this is an easy fix and can be implemented soon - it's crucial for
Masked Brush creations.
