Michael, I often run into text mipmap issues when I use an ATI card. To get around it I always set the env var OSG_TEXT_INCREMENTAL_SUBLOADING to off and it solves the problem. Im still running the osg 2.0 series.

Hi all,
is mipmap gen. still an issue with ATI cards, or is OSG code working
around an outdated problem?
In osgText/Font.cpp line 631 and below the comments are describing the
problem, but obviously subloading all glyphs at once still does not work
correctly on ATI.
Is someone here familiar with the problem and developing on ATI?
I would also like to know if this issue could be solved with reasonable
effort and if this has any priority in further OSG development?
regards,
Michael.
