Version: 1.8.4.0+dfsg-1build1 Hello,
seemingly the same bug is observed using pymol 1.8.4.0+dfsg-1build1 on Ubuntu-18.04. The greeting message of pymol tells that my graphics driver is blacklisted: Detected OpenGL version 2.0 or greater. Shaders available. Detected GLSL version 1.40. OpenGL graphics engine: GL_VENDOR: nouveau GL_RENDERER: NV137 GL_VERSION: 3.1 Mesa 18.2.8 Detected blacklisted graphics driver. Disabling shaders. Detected 24 CPU cores. Enabled multithreaded rendering. Best, Andrius -- Andrius Merkys Vilnius University Institute of Biotechnology, Saulėtekio al. 7, room V325 LT-10257 Vilnius, Lithuania
