Hi,

When I turn hw acceleration off using the troubleshoot tab, the window is jerky to update.

However if I wiggle the mouse around, the contents update smoothly. It is using SDL, but I am sure its a phenomenon someone has come across?

What hacks / ideas do you have to make it stay smooth short of the user wiggling the mouse all the time?
