I am at rc.7 and the problem is still there. But maybe you can get away 
with "user error". Here is a picture of the layout of my laptop:

Lets call the blue thing ts. The buttons directly beneath the keys ts-l 
and ts-r. For the touchpad tp, tp-l and tp-r. And because one can never 
have to many input devices um, um-l and um-r for a usb mouse.

When I play kpatience and stick to one device ts or ts-l or mp and mp-l 
no problems arise. I can also mix devices for example um and tp-l. There 
are several combinations. Only one of these ts and tp-l show the 
problematic behavior. This is the way i use my laptop (user error?)

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.
