I believe that this is actually a KWin problem, when I use Compiz instead of KWin
It's not a KWin problem, it's a KWin feature. In FS, compositing is disabled (as it should be.) No compositing, no VSync from the compositor. Flash does not do VSync, even though it should, because Flash, for whatever crazy reason, does not use Xv, nor OpenGL for rendering. It just copies pixels to the X shared memory. That is the slowest and stupidest method of doing video, and Flash picked that. IMO, the Flash Linux devs are morons.

Unfortunately, Compiz is dead. Distros are now removing it from their repos. Gentoo, openSUSE, Fedora already did that. I'm using Gentoo.

You will not be able to use Compiz anymore in the very near future.
