Here is a fix for the grey-bar bug, i.e. randomly only the current
paragraph is drawn and everything else is greyed out.
I think it is related to synthetic mouse event. Somehow a redraw is
triggered, but the ViewMetric.update_strategy is set to NoScreenUpdate.
The two condition, that I change in the patch, evaluate to true and the
grey bars are drawn.
Here is a backtrace of the issue:

It happened with two footnote in the view, just moving the mouse around.
So could it be related to the mouse hover maybe?
Looks like a good analysis.
I think though that the change in the patch is reasonable nevertheless.
The comparison to SingleParUpdate is wrong. The drawText function must
work with every update_strategy.
I think you're right Stefan and the problem is most certainly caused by
a combination of mouse hover and SinglePar when the focus comes back.
