The full history of the problem can be found on https://bugs.freedesktop.org/show_bug.cgi?id=16866 I'm pretty sure mesa is to blame here, and I have proposed a patch, which will hopefully be accepted and backported into distributions such as Ubuntu. In the meantime, we may need to work around this in K-3D. The solution I have in mind is to flip the culling in GL_SELECT mode to GL_FRONT instead of GL_BACK only on affected platforms. In order to properly define the list of affected platforms, I need everyone who experiences this bug to post the output of the following shell command: glxinfo | grep OpenGL Cheers, -- Bart |
