Short answer: nothing is printed.

Before the issue starts happening, I see -1 and +1 for each wheel
"click" and lots of 1.79769e+308 values when moving the mouse.

Once scrolling stopped working, mouse wheel turning leads to no output
any more (but the 1.79769e+308 values are still printed).

What I was also noticing: when turning the mouse wheel over the scroll
bar, there is a visual feedback: it looks like the scroll bar would lead
to a scroll (the bar moves), but scrolling is not happening, the buffer
text stands still.  Also that is happening without output for DELTA.

Michael.
