This bug report originated from issue QTBUG-4546
http://bugreports.qt.nokia.com/browse/QTBUG-4546

--- Description ---

Reproduced on Linux when building with -static (so that jpeg images are not painted):

- Run the Fancy Browser example. It will show google.com as the start page.
- Select "turn images upside-down"
- It will animate the rotation of the grey rectangle which is in place of the Google logo.

 Some pixels from the stroke of the rectangle are not erased in the animation.

Don't know about the static build, but I get painting artifacts both on Linux (big black rectangle that covers the extent of the image while it's rotating) and on Mac (the rotated image erases part of the focus rect for the lineedit).

This is a problem in Qt's X11 paint engine and is unlikely to ever be fixed. Use the raster engine instead (will be the default setting in Qt 4.8) and everything will look better. :-)
