When setting wmode to "opaque" (or transparent) my flash app becomes slow on Facebook. I can particularly notice it when moving the mouse around (even on a tiny area of the screen), if I don't move the mouse then the slowdown doesn't seem to happen. Maybe its because its sending all events to facebook too?
When using wmode=window then it works fine.
The reason I want to use opaque is to be able to display Facebook overlays on top of it, and so the Facebook dropdown menu doesnt get hidden by the flash object.
Thanks.
