When running either xf86-video-intel git master or the recently release on a non-GEM non-KMS kernel (2.6.26, specifically), I get what I think can pretty accurate be called text insanity. Some text doesn't appear, some text is the wrong color, and some text gets fixed when various things are done to it (like selecting it). Insanity abounds.

Possible to git bisect where the badness happen?
Comment 2 Ari Entlich 2008-12-16 17:51:59 UTC
I'll see what I can do.
Comment 3 Ari Entlich 2008-12-16 19:02:12 UTC
Behold, the guilty party:


Dontcha hate it when it's a performance fix. :-/

Here's a picture. As you can see, a lot of text is missing, and Firefox's title bar text is the wrong color (white instead of black, most of the color mixups are white/black mixups).

Fixed in current master. Tested on T61 with 2.6.26 kernel.

    Don't count vertex buffer in second aperture size check
    With batch flush notify vertex buffer will be unreferenced,
    so don't count it in later aperture check. Also adding
    uninitialized vertex buffer check in batch flush notify.

Confirmed, issue is not reproducible with current git master. Thanks!
