This might be because others are not using Qt5 at all. It's strange, but
understandable in case that newer Qt5 is using chromium as a web backend and
it is not compileable to anything except x86 and arm and this renders Qt5
almost unusable in modern cases.

The older installation on G5 is working the same in all users (tried new one).
The G4 installation on powerbook is the fresh one.

Both installations are independent and on older one (G5 one) I've tried
several users.

Reading the bugs there I've found that it is possible that the problem is in
QXcbAtom::ButtonWheel* wrong detection. I'm yet unable to find how does Qt5
detects wheel buttons and where from it is getting the mouse events.
The xinput shows everything ok, and Qt4 and GTK2/3 apps all are using the
wheel perfectly
Regarding the bugreport. I should register on the site and when I will fill
bug report I'll attach it here.
