Can you post the backtrace? GL_NONE is a valid value for glReadBuffer() and there seems toe be plenty of Piglit tests using this so you might be hitting some corner case here. Created attachment 92646 [details]
Full backtrace
The source code line in
Ogre::GL3PlusFBOManager::_createTempFramebuffer ()
at /home/mega/elbatriq-linux/Ogre3D-sources/Ogre3D-source/RenderSystems/GL3Plus/src/OgreGL3PlusFBORenderTexture.cpp:186
is glReadBuffer(GL_NONE)
Fixed with commit f7c118ffbfdafaccd4ec05d4a040d07e120c5090 |
