Description jmf 2015-08-27 15:17:57 UTC

When transforming a vector layer, like scaling up or down and then trying to transform again, the preview of the transformed image isn't right.

Reproducible: Always

Steps to Reproduce:
1. Create a vector layer and draw something on it
2. Scale it up/down or perspective transform it with the transform tool.
3. After confirming the transform, transform again

Actual Results:  
The preview shows the image before the first transform. Transforming properly becomes impossible.

Expected Results:  
The preview should show the image after the first transform, so scaling preview actually shows the end result.

Hi. I think I can confirm, it happens with vector layers specifically, as you've said.
Please, could you check the attached video (1min., sorry) and tell if it illustrates the bug you described?
Thank you

Yes, that's the bug that I mean. 
Thanks for the video.

Comment 3 Halla Rempt 2015-09-12 09:34:06 UTC

Yes -- there are more issues, though, saving a transformed vector layer also doesn't work.

Comment 4 Dmitry Kazakov 2018-02-07 19:12:38 UTC

The issue is partially solved now, at least the preview coincides with the final result now. Though the tool still doesn't hide the original (untransformed) shapes.
