Backtrace while running with --enable-debug showing assert_fail()

Well, it looks like we closed #46346 a bit prematurely.  I got another assert_fail in sna_pixmap_move_area_to_gpu().  Backtrace is attached.

Feel free to merge this with 46346 if that's how you'd like me to handle it in the future.

Thanks,
--Joe

Another backtrace

Here's another backtrace showing a similar (to me) assert_fail.
Comment 2 Chris Wilson 2012-02-22 01:11:42 UTC 
It is a subtly different assertion failure. On reflection, it looks like I relaxed an invariant that the assertion is checking...
