Description Wolfgang Jeltsch 2006-12-29 00:37:32 UTC 
Version:           1.6.1 (using KDE 3.5.5, Debian Package 4:3.5.5a.dfsg.1-5 (4.0))
Compiler:          Target: x86_64-linux-gnu
OS:                Linux (x86_64) release 2.6.18-3-amd64

To reproduce this bug, please run “krita http://v791.vanager.de/jaromir.jpeg” and then try to rotate the image or layer by selecting Image -> Rotate -> Rotate Image CW/CCW/180 or Layer -> Rotate -> Rotate CW/CCW/180.  In all cases but rotating the image CCW, a chess board pattern is introduced in some parts or even all of the image.  (Does this chess board pattern mean something like transparency?)

Yes, that's transparency. Please use koffice@kde.org for user related questions.
Comment 2 Wolfgang Jeltsch 2006-12-29 14:23:07 UTC 
Thank you for your answer.  However, even if the chess board pattern denotes transparency, the behavior I described is mostly incorrect, in my opinion.  If I tell Krita to rotate the above-mentioned image by 180 °, for example, I expect Krita to generate a rotated version of this image and not a completely transparent image.

Confirmed, unfortunately :( (1.6 branch, r614151)
