How to disable mouse click when hover

Hi all,
I am newbee for Manjaro. I installed Manjaro on Raspberry Pi4 with touch screen. Somehow today my mouse started to click when hover on a clickable component. I want to disable this feature but couldn’t find how to do, etiher how the feature was activated. Please help me.

See in System settings WindowsWindow behaviors and, if you have installed, KMouseTool settings.

Thank you for reply. I found that the problem is about third party software: Onboard.
