I'm using Linux Mint 17.1 (Cinnamon) and I'm experiencing an annoying lagging when pressing the left mouse button on my laptop's touchpad. The lagging does not appear when I connect an external (USB) mouse or use other external peripherals. It feels like a delay of half a second (so in the range of milliseconds).
It's not always noticible but a typical situation would be when I'm trying to select text in a document and the selection would always start in the middle of the word I'm trying to select (i.e. moving the mouse cursor from left to right). Or when I'm trying to move a window and I'm moving away the mouse cursor too fast from the window frame then the window wouldn't follow.
When I boot Win7 on my laptop and start the same Linux Mint version as a virtual machine I do not experience this lagging. Thus it seems that my hardware is not the cause.
I was also checking LM's mouse settings but it seems there's no option for mouse click delays or anything related to that.
Could some explain what's going on and how I can fix it?
