Strange Behaviour - Control Behaviour is set when moving mouse wheel

[magicstar]

Hello,

I have created a dialog which has 2 horizontal sliders and some other widgets. I want to disable default mouse wheel behaviour on sliders and handle mouse wheel event through eventFilter.

However, I see strange behaviour. When I am moving mouse wheel, control modifier is getting set.
I am not sure why it is happening .

Does anyone know solution to this problem ?

Do you have the same behaviour with an USB mouse ?

@SGaist , No. The issue is not coming with USB mouse.

Then it might be something that is specific to your mousepad driver.
