Bug ID: 436721
Summary: Flattening an animated layer with layer effects gives
artifacts
Product: krita
Version: nightly build (please specify the git hash!)
Platform: Debian stable
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Animation

Animated layers with layer styles
SUMMARY
If an animated layer has layer effects on it, then for some effects there are
artifacts created when the layer is flattened. Attached example .kra files are
provided.
This is seen with the May 06 5.0.0-prealpha (git cb99b9e) appimage and also the
4.4.3 appimage
STEPS TO REPRODUCE
1. Create a simple short animation and apply the layer effects Bevel or Drop
Shadow to it (or use the attached Anim-FX.kra file which has Bevel, Drop Shadow
and Satin layer effects on separate animated layers).
2. Flatten each layer.
OBSERVED RESULT
2. Artifacts are created when each layer is flattened.
(The file Anim-FX-Flattened, produced with the May 06 5.0.0 appimage is
attached.)
See Additional Information for more details of the observations.
EXPECTED RESULT
2. There should be no artifacts created.
ADDITIONAL INFORMATION
a) For the attached example, the flattening was done when frame-4 was selected
and it seems that this frame has the least number of artifacts.
b) When the Drop Shadow Fx layer was flattened (before the Satin Fx layer was
flattened), a temporary artifact was created over the Satin Fx layer image on
frame-4.
Then when the Satin Fx layer was flattened, only frame-3 of the Satin Fx layer
had artifacts on it.
c) For an animation with a single layer that has Satin Fx on it, flattening
gives no artifacts but the frame that was selected when flattening was done has
no Satin effects on it.
d) If a layer style is changed to another effect, any selected frame will show
the new effect but when the animation is played then the previous effect is
shown. This has been observed for changing from Satin to Bevel.
e) In some cases (but not repeatable) flattening a layer with effects gives one
or more Held frames instead of painted keyframes on the timeline.
