Exact same problem occurs for me, with the touchpad, usually when clicking something the pointer shoots to the bottom left corner of the screen. Not every time but intermittently. This is a bug that has existed since 14.04, and I managed to fix it back then, but for the life of me I can't remember how I did it. I think I had to make some adjustments to the synaptic driver config, perhaps even had to recompile something... I've searched to find the solution that I used last time but can't seem to find it now!
