This change did not fully solve the problem. One text file in gedit
displayed as blank initially for a bit, although things then seemed
fine. But the freeze with "[drm] stuck on render ring" happened during a
second run of gtkperf - while the "GtkDrawingArea - Text" test was
running.
But I didn't spot any corrupted characters while running 2.99.907 with
MAX_FLUSH_VERTICES set back to 6 - although I hadn't been running that
for very long, and I only see a single garbled char occasionally, and I
think they only appear in Firefox.
