Not correct.
The driver is fine.
The problem is somewhere in the opengl/mesa stack.
And it is triggered specifically by something in coot, since other programs
don't hit it.
I haven't yet reached the point of desperation since my affected
machines are either (1) non-essential or (2) fast enough so that
a 10X hit in rotation speed is only at the level of incredibly
annoying rather than unusable. But I may get there soon enough if
I need to do much cooting on my laptop.
Rather than killing labels altogether, I think it would suffice to
draw the labels only every 10th frame.
That's still a hack, though. It should be possible to revise the
label drawing so that the problem doesn't trigger in the first place.
