Bug 473468

SUMMARY
When a layer contains a few animation frames and a Stroke effect (and perhaps this might happen with other effects as well), playing the animation and then stopping it will often result in the stroke effect from another frame appearing in the frame it stopped on. Scrubbing through frames will usually correct it.

STEPS TO REPRODUCE
1. Create a multi-frame animation on a layer, add a Stroke effect
2. Press the Play button on the timeline
3. Press the Stop button on the timeline

OBSERVED RESULT
On occasion the stroke effect from another frame will appear in the frame it is currently showing.
***NOTE: This MAY technically be a case where Krita is incorrectly overlapping the frames from 2 layers (one Stroked, the other not).***

EXPECTED RESULT
Stroke or stroked layer frame should match the frame number it belongs on.

ADDITIONAL INFORMATION
The animations where I have observed this use several layers, each dedicated to a different element of the image (linework, color, shadow, and most relevantly, a stroked white silhouette to thicken the contour of the animating object). Is Krita perhaps aligning things layer-by-layer as it plays, only to get its display instructions abruptly stopped, thus misaligning one of the layers?
