Version: (using KDE 4.2.2) Compiler: gcc (GCC) 4.3.2 20081105 (Red Hat 4.3.2-7) OS: Linux Installed from: Fedora RPMs In knetwalk 3.0.0 as shipped with KDE 4.2.2, multiple stray pixels sometimes appear while the rotation of a puzzle piece is animated. The pixels move in sync with the animation (their relative locations compared to the rotating piece remain constant). The pixels disappear once the animation has finished. The problem occurs with both Default and Electronic themes. The pixels appear to be whitish in color. Expected behavior: the rotation animation should occur without stray pixels, as with knetwalk as shipped with KDE 4.2.1.
I can confirm. The pixels aren't visible at smaller sizes, but become quite obvious at larger ones. When playing a game of Easy in a maximised window they're pretty hard to miss.
The bug is still present in KDE 4.3.0 (Fedora 10).
I think it's not a bug in KDE, but in QT 4.5 as I experienced it the first time when I upgraded my QT version.
This also appears in KDE 4.2.2 with Qt 4.6.2.
On KDE 4.10 with Qt 4.8.4 (openSUSE 12.2 x86-64), I am unable to notice it.
Cannot reproduce either, closing.
