Right - but it also suggest that this is trigged by lock-screen, when monitor is shutdown to save power and restarted with a lock-screen. I'll force monitor to be on for a few days for observation.
Lock-screen is a source of various problems for a variety of people. I, for one, have never got it to work consistently on any laptop I've owned.
A final test to see if this is a hardware problem .... within some bounds ... would be to ssh -X to it.
I forget to mention that ssh -X always perform okay (on the X of another host of couse), so it leads us away from fonts and gtk again. But, that only moves suspicion to the X-server, and that could be either a driver bug or hardware problem.
There are two possible classes of hardware probelm, then. One is hardware failure. Perhaps running Windows for a while will tell you about that. The other is hardware comparability with the X server. That breaks down into * genuine bug * fringe behaviour * configuration issue The latter is enormousness since modern video drivers have so many capabilities that can be tweaked in various ways.
