Description Thomas Pfeiffer 2015-05-05 19:34:07 UTC 
Apparently on systems that have touch screens (regardless of whether there is a mouse attached), QtQuick decides not to show scrollbars in scroll areas.
This is not how it should be in Plasma Desktop. When a mouse is connected, it is likely to be the primary input method, so it has to be possible to scroll with it, and the presence of a scroll wheel cannot be guaranteed.
Plus, applications do have scroll bars, so that introduces an inconsistency.

Reproducible: Always

Steps to Reproduce:
1. Run Plasma Desktop on a device that has both a touchscreen and a pointing device
2. Open e.g. the widget explorer

Actual Results:  
No scroll bars

Expected Results:  
Scroll bars present

Disable transient scrollbars

To improve accessibility and consistency with widget applications scroll bars no longer
automatically hide after a timeout, which was the case when a touch screen was present,
which is nice for tablets but bad for desktops.

CHANGELOG: Scroll bars no longer automatically hide when a touch screen is present
