** Description changed:

+ 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 and Frogatto.
+ 
+ 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"
