I am experiencing other problems on the Windows side: Rectangular
textures are messed up by the driver, they get scaled and clipped the
wrong way, when the textured object is fully opaque. I've seen this also
on a dell Laptop with ATI graphic-card. I did not have enough time to do
some more simpliefied tests.

Texture subloading works fine for me on OS X and Mac Book Pro. I am
playing a lot of quicktimes and live video feeds inside osg, works like
expected.
Must be something special what osgText does.
osgText subloads small glyphs one by one rather than the whole image, so I'd suspect it is this that is broken. There is a path way in osgText::Font for uploading the whole image at once, which original was specifically implement as a work around for an Octane driver bug, but for 1.1 I enabled this pathway to be selectable via an env var to see if OSX users could work around the OSX driver bug. I wrote about this previousy on the list. Try:
setenv OSG_TEXT_INCREMENTAL_SUBLOADING OFF
Then run your app. FYI, if you run osgviewer --help-env the above env var will be listed.
Let me know if this helps,
Robert.
