Description kalia24 2015-03-04 08:30:15 UTC

Here's what happened today after lots of stretching/rotating/slanting on a piece of picture:
http://i62.tinypic.com/4q04mr.jpg
The shape behind is the base one. As u can see, it's mostly plain in colour. After transformations (shape in front) lots of random patterns appeared.

Reproducible: Didn't try

Steps to Reproduce:
1. Copy a bit of partially transparent picture (8 bit/int).
2. Do a lot of transformations on it.

Actual Results:  
Random patterns on the surface.

Expected Results:  
Colour remaining like before transformations.

Hi Kalia,

Please -- if you have files to test with, could you add them to the bug report, or put them in a permanent place? What with day job and other things, we sometimes don't have time to download the files in time, I'm afraid.

This hosting is permanent I think (images are still there and I never got any warning about them being about to be deleted). But if u prefer, I can attach them to the reports.

Hm... I couldn't access the .kra file -- so please, do attach. Thanks in advance!

Oh, that one... I was done with that work, so I removed it (totally forgot that it was linked here).
It's back up (can't attach since it exceeds attachment size limit).

I have never seen that, I cannot reproduce it now, the test file is gone and there is not enough information (like which transformation etc.). hence I'm closing this.
@kalia24@wp.pl - if you still has this issue or encounter it again, please reopen this bug report and add test file and more information how to get the bad result.
