I have the following problem with Qt 5.4 under Linux: scrolling events can happen in the wrong direction. For example, I may scroll up but receive a combination of positive and negative scrolling angles. It seems to happen if the drawing is a bit slow in my application. Could it be related to the way events are combined?
Note: Just tried with Qt 5.5, and the problem is still there.

Hi,
Is this something new to 5.4 or did you already had that before ?

I had an old mouse that gave irratic scroll wheel signals. It still worked but I did notice it jumpy when trying to scoll windows on occasion (all windows, not just Qt). I don't know what you are using but I would make sure the problem is not hardware.
