Public bug reported:
Binary package hint: xserver-xorg-video-intel
System: Ubuntu Intrepid (updated from hardy), up-to-date as of 2009/01/14 on
Dell Latitude D620 with Intel 945GM video, 1440x900 display.
Problem: GL applications flicker during display. This problem shows up in a
variety of ways:
1. GL applications 'show through' overlying windows. For example:
-fire up glxgears
-place a console window (or kate, or firefox, or anything) over the top. The
glxgears window decoration is covered, but the glx display window itself is
always on top, effectively showing through the overlying window.
This occurs for a number of gl applications, including the screensaver preview
box on the screensaver configuration app.
2. GL applications show 'flicker boxes' - these appear to be semi-random
in location and size, but are always rectangular, and flicker back and
forth. When I run a full-screen GL application such as Celestia or
Stellarium or (sometimes) a screensaver, I get funny boxes showing up,
flickering, disappearing. (example photo attached - from Celestia, two
boxes in upper left (one small, around text, one about 640x480, the
other in the lower right, appearing white). Googleearth has so many
artifacts it is unusable.
3. GL screensavers often (not always) display as if on a 640x480 screen.
This results in something like an left-hand upper quarter screensaver,
with a grey or black field for the rest of the screen (see attached).
