Public bug reported:
Binary package hint: compiz
I have an up-to-date i686 gutsy install on a Dell XPS M1710 laptop with
an NVIDIA GeForce Go 7900 GS, except with some packages installed from
hardy--specifically, the NVIDIA drivers. When compiz is turned on, I
frequently see a couple different types of visual corruption of window
title bars, some of which is new to the 169-series of NVIDIA drivers
(i.e., does not occur with the version in gutsy). The corruption can be
triggered in several different ways: (1) change of window focus (easy to
see with UNIX-style focus), (2) mousing over the buttons at the top-
right or the one button at the top-left, and (3) change of window title
(e.g., changing tabs in Firefox). The corruption can broadly be
categorized into one of three types: (1) sometimes the title bar becomes
grey, perhaps with the title and/or one or more buttons disappearing;
(2) sometimes the title bar becomes a translucent red or a translucent
blue; and (3) sometimes the title bar disappears entirely (except for
the one button that the mouse is over). Prior to upgrading to the
drivers in hardy, I only observed the first of these.
The corruption occurs with all of the themes that I have (which is just
the default ones that come with Ubuntu), but it is much more common on
Clearlooks-based themes (particularly Human). Additionally, on non-
Clearlooks themes it is situation-dependent, in that in may only occur
in specific ways on specific windows for specific periods of time,
whereas on Clearlooks-based themes it repros very reliably. It is also
far more common for it to happen on maximized windows than on non-
maximized ones.
Note that there are at least a couple other open bugs that are very
similar: bug 99508 and bug 152493. The key differences are that I see a
wider range of corruption modes and that I also see them on non-
Clearlooks themes and non-maximized windows, whereas the others are
apparently exclusive to maximized windows on Clearlooks. (I originally
reported my issues in comments on bug 152493, but I have been requested
to file separately.)
Currently I am using NVIDIA TwinView, but I have seen this both when it
is on and off.
