Description
The attached code creates JFrame which updates shape in componentResized method. When this window is resized on Windows Vista Aero it shows a lot of unattractively looking repainting artefacts making the whole feature doesn't look attractive.
Comments
EVALUATION With a fix for 6993784, which is currently in progress, a decorated window won't be able to become shaped, and therefore the provided test won't run throwing an IllegalComponentState exception on a call to setShape(). Therefore I'm closing this bug as 'Not a Defect'. If a similar issue is still reproducible after 6993784 is fixed and integrated, feel free to re-open the bug and provide an updated test.
