[Bug 1892133] [NEW] cursor flickers/disappears and windows resize or move randomly

[Barmak Nassirian]

Public bug reported:

Ubuntu 20.04 natively installed on 2013 Google Pixel Chromebook (i.e.,
it is the only OS on machine)

Installation went fine, but after a few minutes of use, the cursor
begins to act up--flickering and sometimes disappearing altogether. Even
more problematic: Firefox windows resize on their own or move. Sometime
moving the cursor moves the resized windows (as if I am clicking and
holding the menu bar) and sometimes not.
