Public bug reported:

While using the 'eraser' pointer on my Dell Latitude E6540, the cursor
will sometimes instantly jump around randomly and open a few windows.
After this happens, it will become completely unresponsive for 10-20
seconds.  Sometimes the keyboard will stop responding also.  It seems
like it is most likely to happen when I bump the trackpad with my palm
when using the eraser pointer in the middle of the keyboard.  Also - I
have always had the trackpad disabled when this happens via the Dell
hotkey (Fn-F5).

Of course, it has never happened when the laptop is docked and I am
using an external keyboard/mouse.

This issue seems identical to Bug #1258837.  On that page @penalvch says
to file new bug reports to capture the hardware, and to mention him :).
