Description acc4commissions 2022-08-07 12:06:56 UTC 
SUMMARY
git 9901f95

It has been happening for a while.
The title says it all. 


STEPS TO REPRODUCE
1. Select an area or just select the layer and trigger the transform, and make sure that you're using 'Fast' preview option.
2. Press arrow keys to move it.

OBSERVED RESULT
The preview on the canvas doesn't update. However it applies when the transformation is done. 

EXPECTED RESULT
It should show. It used to.

ADDITIONAL INFORMATION
Comment 1 Tiar 2022-08-10 11:51:52 UTC 
It worked fine in 5.0.6, but is broken in Krita 5.1.0-RC1.
Comment 2 acc4commissions 2022-11-17 17:45:08 UTC 
Can this be fixed anytime soon? It's a small issue but it's really pesky;
I can't really use other preview modes other than Fast, because Liquify becomes basically unusable with those.
Comment 3 acc4commissions 2023-03-15 12:58:02 UTC 
Hope this one is addressed in 5.2.

Before this commit, transform tool wouldn't update the canvas
when the user used arrow keys to move the content using
the Fast preview type.
