Bug Description
I have the dock on the left side of my screen. When I continuously move the cursor along the left edge of the screen the dock can't decide whether to hide or show and starts to jump in and out.
It's a single screen setup, MBP 2015 Retina, and because of that I have "scale for menu and title bars" set to 2 in ubuntu system settings. Therefore my best guess was initially that the culprit was integer rounding errors in subpixel calculations, but it looks to be incorrect. I noticed that the issue only appears when I use the force touch trackpad, and not when I use my logitech usb mouse. I don't know how to provide meaningful info about the trackpad though. All I know is that the speed at which I use the trackpad is key. The slower I move the worse it gets. If I move quickly the behavior is pretty much normal.
Distribution
Ubuntu 16.04, pretty much vanilla
Window manager
The default, compiz I guess...
Version
0.11.1.1555

More info
The problem only seems to occur when the screen edge (left in this case) is the furthest away in a multimonitor setup. I.e. I can make the problem go away by adding another screen whose left edge is even further to the left. (The two screens are otherwise arranged vertically, one on top of the other, just not with aligned left edges)
