krita painting artifacts in animation frame

There seems to be some problems updating the canvas while animating.

Typically, if a frame is moved or new art added to it, it takes a moment to generate a new 'preview' (not sure of the nomenclature). However, in the timeline, the first frame (0) and any other frames before the next key, don't update. No grey marker above the column.

Possibly (un)related, on the canvas, new art starts to look like the attachment. Pixels where new art is drawn are the only ones updated. Hence, the peculiar artifacts.

I believe it's related because after a number of keyframes with new art are added, and if onion skinning is turned on or off, Krita is slow to update the frames (or previews). This makes it difficult to scrub quickly thru the animation, thus making it difficult to animate at even a moderate pace.

I love the direction Krita is going with animation, but it must be faster at updating the previews. It needs to be instantaneous and not be in the way of the animator.

I guess you get these artefacts and that it's on the slow side because you haven't got opengl enabled? If you update to a newer version of Windows, you will be able to use gpu canvas accelaration.
