I just learned that there is a workaround, which seems not to be well documented (or not at all), but which works:
Add (xor-color (color-rgb 1.0 1.0 1.0)) to .gimp-2.4/gimprc I am not entirely sure whether this is a bug of gimp or particular graphics drivers. If the latter one is the case, the bug may be closed but I would welcome some FAQ/README entry in the docs which points to the workaround. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
