Bug ID: 496869
Summary: Broken "Normal" blend mode in layer styles of 16-bit
integer image
Classification: Applications
Product: krita
Version: nightly build (please specify the git hash!)
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: layer styles
Assignee: krita-bugs-n...@kde.org
Reporter: chirn...@hotmail.com
Target Milestone: ---
Created attachment 176245
--> https://bugs.kde.org/attachment.cgi?id=176245&action=edit
image illustrating the problem
Git hash: 74d5360
(worked OK in at least 292fd73, possibly newer nightlies as well but haven't
tried those)
STEPS TO REPRODUCE
1. Create a new project in 16-bit integer color depth.
2. Make a dark background then create a white shape on a new layer (raster or
vector)
3. Apply a gradient overlay layer style to the shape with a "Normal" blend mode
and a white to black foreground to background gradient.
OBSERVED RESULT
It should look pretty obviously messed up. Other blend modes like multiply seem
to work OK.
See attached test image. The two left shapes use Normal blend mode and the
rightmost shape is just a vector gradient and unaffected.
