It's certainly on our TODO list, but I can't make specific promises if/when it'll happen right now.
FYI, to get rid of the tearing, you can either:
a) Disable the X composite extension
b) Run a compositing manager, and make sure the compositing manager's rendering is set up to sync-to-VBlank (e.g. via OpenGL settings)
