It's somehow a fundamental problem. AFAIR David has already thought
quite a lot about it, there is no trivial fix for that right now,
though. The problem is that the off-screen surfaces have to be resized,
which is a costly operation. It's also expensive on higher end hardware,
just not as noticable.
I think in the near future the resize plugin can do something about it
(an intermediate off-screen surface during resizing, doing the final
size in the very end), but nothing right now.
