Strange behavior on window maximize

[Alexander Lazarević]

When I maximize the window the content is not redrawn. Only if I move the mouse over the window some elements get redrawn.
When I put the window back to the original size the window starts slowly shrinking in width while flashing it's content. In the end there is a just 1 pixel wide window left. After resizing the window this starts again and stops with the same 1 pixel wide window.
This makes EToys somehow unusable on Ubuntu
