Update: if I switch AppArmor to complain mode, the refresh problems
disappear. Here is a syslog excerpt with the AppArmor audit lines
(notice the third one about /dev/nvidia-modeset):

Title:
refresh problems with multi-process
Status in firefox package in Ubuntu:
New
Bug description:
With Ubuntu's build of Firefox 51, enabling multi-process produces
refresh problems when switching tabs. In detail, here is what I did:
1) create a new profile
2) start firefox with that new profile (so no add-ons)
3) display "about:support" and check that multi-process is on
4) open a few other tabs on various web pages
5) switch between tabs: most of the time, the display is not refreshed, the
old tab's contents is still there
Then I tried Mozilla's officiel build of Firefox 51 for Linux
(specifically the French x86-64 version), and I had no problems:
display is refreshed when I switch tabs.
There must be something different in the Ubuntu build. Note I have a
NVidia card and use the proprietary driver (I'm assuming detailed info
is uploaded as part of the bug report process?).
Additional information: I have Ubuntu's AppArmor profile for Firefox
enabled.
