noone complained so far? If it was a general problem and/or a problem with
the nvidia drivers probably people would already have filed a bug...

I don't see slowness in your video?

Also OpenGL off?

There's always the option of not using those. There's actually no reason to use
those, imho. Try with the free drivers, and if the problem goes away fine.

Needless to say, works fine here. (Intel.)

moreinfo, unreproducible. I "hate" such type of "bugs" because there's nothing
really to do here, you use a proprietary driver not in Debian and noone really
can do something about it.
