(Get the code!)
Can you try the gl backend in real world usage? I expect it to fail as well, as I think the failure mode here is the machine dying whilst waiting up a scanline - and both the Xv and gl backends should trigger that code. (Except in the case of fullscreen gl, which will go through another path). Whereas the X11 backend will not (and also will not actually use the GPU).
In a very recent -intel DDX update, I've coupled Option "SwapbuffersWait" "false" to disable the vsync for the Xv backend as well. You can disable that through an Xv parameter -- provided it is exposed by the client. That will be very useful for testing whether the scanline wait is the root cause.
