Comment 189 for bug 1098334

I have been experimenting with various numbers in the code in comment #157 without really discovering anything useful. I think any change that slows things down decreases the chances of observing any corruption, but might not necessarily fix the problem completely.

With current git + MAX_FLUSH_VERTICES=6, gnome-terminal suffers from the text corruption, firefox is bad, but KDE4 konqueror and MiniBrowser from webkitgtk3 seem to display the same webpages perfectly fine. The other thing I have noticed is that under this setup, I can make gedit suffer from the text corruption if I set an italic (and not monospaced) font - in that case, almost every line of the text file displayed will show some corruption immediately after changing to the italic font.
