This changeset:
should make things significantly better/smoother for your use case.
Let me know how if this helps.

Are you still testing with glxspheres? The tearing is gone here, but I
am only getting about 15fps from Xdummy, pale in comparison to what you
must be getting from a GPU.
With the new code and mmap enabled, I can get about 80fps at 800x600
through xpra, which isn't bad.

Do you have a simple test case I could use to reproduce?
Do you happen to know which X11 calls are made to change the id?
