Wrt the INVALIDATE_BUFFER issue, this seems to be a threading problem. If I
disable VBOs and fill the buffer with random garbage(or zeroes, or ones) I get
no corruption. I suspect when one thread invalidates the buffer and writes new
data into it, the update isn't properly propagated to the other thread(GL
context) and it draws from the old buffer content.
