How to disable KDE Windows preview?
I just turned to Kubuntu straight from Windows so even basic stuff here is a little difficult for me.
When I point my mouse at any task in a panel, an annoying window comes up and I want to turn it off somehow. Please tell me how can I do that. I'm using the latest Kubuntu 15.10 I think. Thanks
Right click on the panel (Not running application) -> Task Manager Settings -> General -> uncheck "Show Tooltips"
To disable KDE Windows preview : right click your taskbar and select Task Manager Settings. In General tab, uncheck Show tooltips and save with Ok.
