Hi Agustin,
Yep, I had the same problem with OSG 1.2. Major texture shift in x
direction. Still using OSG 1.1 for creating paged terrain.

Hi Robert:
Thanks for the quick answer. But I'm not talking about one or two
pixels. Look at the images LOD0 and LOD1, with 1 and 4 drawables. In the
first LOD level, there exist a broad black rectangle on the right part,
and the two right textures have been shifted to the left a lot of
pixels!!

Hi Agustin,
GDAL uses nearest neighbour technique to get texels from source
imagery, it doesn't smooth them, or doing any averaging when down
sampling data. This does lead to some loses in imagery quality,
including single pixel shifts.
With GoeTIff files you can build overviews which help reduce this
artifacts.
Robert.
