Some screen corruption appears in firefox's tab titles (screen shot attached)
after resume from suspend to ram.  Restarting Xorg resolves the corruption.  I
have not seen the problem without doing a suspend, even VT switch doesn't seem
to trigger it.  This might be a dupe of 66990, but no one mentioned suspending
in that thread.

Reproduction steps:
   Start X, open firefox with 3 blank tabs, open an xterm (or whatever)
   Enter system sleep and resume
   Move the mouse back and forth across the tabs.

A git bisect found this commit as the origin:
bad: [8d48a43ed956ff21d779aff1a11a0f7bf6b65bcb] sna/gen7: Refine ring selection

However, reverting only that commit on the latest driver (commit 76790db) does
not fix the problem.
