I have the problems with the AMD cards only. Sorry, but I have to correct myself, because the problems I have reported in this thread are also present in my currently working release branch (fc7990001035efeeae4458cb582e1a2abf6579a9) in which I use the following flags OSG_ENABLE_OGL_VERTEXATTRIB_FUNCS=OFF OSG_ENABLE_NEW_GEOHANDLER=OFF If I change these options to ON I also see them there. I oversaw that as I wrote the report. However, as I have reported in the other thread (http://sourceforge.net/p/opensg/mailman/message/32363721/), with the above settings (OFF,OFF) my last OpenSG checkout (533aa767fd59a0db446b6639fd9cccbdea577865) does not work on the AMD hardware. This is (may be) a regression from the (fc7990001035efeeae4458cb582e1a2abf6579a9) checkout. At first iteration this is the more serious problem, because it stops me from synchronizing. But let us come back to this in the other thread. Otherwise it is going completely confusing :-) So here we have: 1. OSG_ENABLE_OGL_VERTEXATTRIB_FUNCS=ON OSG_ENABLE_NEW_GEOHANDLER=ON 2. Only AMD 3. fc7990001035efeeae4458cb582e1a2abf6579a9 533aa767fd59a0db446b6639fd9cccbdea577865 > > Thanks.

My geometry setup is pretty simple.
