There is one known issue with fullscreen video playback in this build, if you move the mouse to the top of the screen to make the player controls appear, they sometimes (or most of the time) show up in the center of the screen instead, and you can't use them.
Additionally, it'll also bring the desktop environment's controls back at the same time, which is kinda annoying.
Just wanted to let you know before I get numerous reports about it. 
PS:
Did I mention that this antiquated X stuff on Linux is really annoying? Why is this still using a desktop tech from the 80s anyway?
Hey bob, why did we ever decide to talk to X directly? 
To maintain the ability to do skinning amongst other things.
If the low level stuff worked right (and was documented properly in something other than a 10 year old unavailable book) it would be easier...
We could always switch to xcb, even less documented and even lower level!
