HI Li, My best guess is that the first cut of fallback shaders I've added for GLES2/GLES3 and GL3core are being enabled accidentally for some reason. These shaders shaders are add in the StateSet::setGlobalDefaults() method implementation found in OpenSceneGraph/src/osg/StateSet.cpp. Could you put an #if 0 #endif around all the shader code in StateSet::setGlobalDefaults(), do a build and see if that restores the rendering back to normal.
These fallback shaders are there just to make sure there users see something on screen when no fixed function pipeline isn't available. I'm currently working on a experimental shader_pipeline branch of the OSG that has support for intergrating #pragmat(ic) shader composition with fixed function StateAttribute to get pure shader based builds to work in the same way as fixed function systems so that old fixed function based models work in shaders without problems and no need for generating shaders manually. For this dev release that shader_pipeline work won't be merged, I was hoping that the fallback shaders in OSG master wouldn't affect standard OSG builds, if it isn't I'll need to have a look at how the #idef's are all put together.
