Thanks for the detaied reproducer, I can reproduce this on my Dell d620,
I will investigate further and go back to you.

> Now something to distract you from the issue, something almost completely different. Something which is also present in 3.18 and probably before. Firefox and other programs have scrollbars on the right side. One can click on it, move the slider and release the button. Except with the combination tp and ts-l, It does not work. Al other combinations do.

And this one I can reproduce too ...
