1 I have this card:

3 rpbarlow@lappy786 ~ $ /usr/sbin/lspci | grep Graphics
4 00:02.0 VGA compatible controller: Intel Corporation 82852/855GM
5 Integrated Graphics Device (rev 02)
6 00:02.1 Display controller: Intel Corporation 82852/855GM Integrated
7 Graphics Device (rev 02)

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