Thanks for checking!

I tried to make an apitrace of how matlab uses our driver, but it did not fare
well (just a ton of commands, but no swapbuffer IIRC) and I took interest in
something else.

If you manage to get useful apitraces of what matlab does, we could run them
and check for crashes and changes in rendering.
