SDL window gets erratic behavior when resizing itself under compiz

Bug Description

SDL apps that resize their own windows get stuck flickering rapidly between different sizes. This makes the app unusable and is not always recoverable.

Confirmed with:
  - QEMU/KVM: When the VM changes video mode.
  - Frogatto: When entering the editor.

ORIGINAL DESCRIPTION:
This issue affects Frogatto: 2d adventure game, #frogatto on freenode, www.frogatto.com
When entering Frogatto's editor, which uses a different window size, Unity gets stuck flickering between the game's window size and the editor's, for several seconds, until settling on either.

Given the following exchange on #ubuntu-unity, this issue also affects QEMU and KVM, which also use SDL for graphics.

<thumper> marcavis: what toolkit does the editor use?
<duflu> marcavis: I've seen the same bug happen with QEMU/KVM windows. It's probably compiz to blame.
<marcavis> hmmm, makes sense... Frogatto just uses SDL/OpenGL, no specific GUI toolkits
<duflu> marcavis: Yes, QEMU/KVM uses SDL too
<duflu> marcavis: I can't remember if there ever was a bug for it. Please log one with "ubuntu-bug compiz"
