Description
WComponentPeer#setBounds() can set paintPending flag if the method is called twice with the same size. Since JLightweightFrame gets size arbitrary from an external call the paintPending may be set to true even when paint event from the previous size change has not been handled yet. As result the frame content is not painted at all.
Comments
There is no testcase or steps mentioned to reproduce the problem, so marking it as Incomplete for now.

so far we don't have a consensus how to fix it based on review, no time resources to fix it in 9. Defer request.
