Bug description:
Sometimes getting incomplete drawing of same glyphs of one font on
whole screen.
In the screenshot you can see the "e" is drawn incompletely (both
english and cyrillic too).
The bug is happening frequently and spontaneous on my Asus EEEPC 900.
(This issue affects Ubuntu's 10.10 or later. A workaround using the
DebugWait parameter is described in comment #40 -
