 this before?  I don't know what other programs I can test it with that I
 might be able to get a screenshot to show you with, but if anybody knows
 something that might be a good test, let me know!

You could test downgrading x11-drivers/xf86-video-i810 to 1.7.4. as
there were some problems with i810 after the last x11 upgrade.

[gentoo-user] Bad 3Dness from my Intel 855GM!

2007-09-19 Thread Randy Barlow
I have this card:

[EMAIL PROTECTED] ~ $ /usr/sbin/lspci | grep Graphics
00:02.0 VGA compatible controller: Intel Corporation 82852/855GM
Integrated Graphics Device (rev 02)
00:02.1 Display controller: Intel Corporation 82852/855GM Integrated
Graphics Device (rev 02)

The problem is that it renders 3D scenes incorrectly, frequently putting
objects that should be in the background in the foreground.  The only
time it really happens that I've noticed is in the 3D xscreensaver
(using kde's screensaver as the front end) screensavers.  For example,
the one that plays chess - if a pawn is closer to you and behind it is a
king the king will appear to move in front of the pawn as the board
rotates, when it should move behind it.  Has anyone seen anything like
this before?  I don't know what other programs I can test it with that I
might be able to get a screenshot to show you with, but if anybody knows
something that might be a good test, let me know!
