Great catch! Currently the logic of the scrollbar is unclear to me.

Under the hood there is an inaccurate information (passed to Qt) about
the visibility of the scrollbar. It is a kind of oscillation between
"it's visible" and "it's not visible". The patch fixes it but it
amplifies another problem.

If the c++ code is without double somersaults, I'll be happy to find a
happy ending.
