Hi, George We run into same issue yesterday, and as far as i can tell, this changed between osg 2.9.9 (all works ok) and 2.9.10(nothing visible). osgText is culled when it shouldnt for some reason. For temporary solution you can turn off culling on geode with text or add some other drawable as u did.
