hmm, I can't find anything obvious that would explain it. Could you
check if in Viewport::render() the correctly modified matrix is obtained
from getCamera()->getProjection(m, width, height) (around line 393)?
That would narrow it down to whether the problem is in calculating the
correct matrix (i.e. it is on the decorator side) or if it is related to
which matrices are used for rendering (i.e. it is in
RenderAction/RenderPartition and related code). Thanks!
Cheers,
Carsten
