Resolution: → can't reproduce
Status: assigned → closed

ChimeraX 1.6 on startup on Linux calls make current on the Qt QOpenGLContext without errors and then PyOpenGL says it can't get the current context. I've only ever seen this on Linux. It may be a Qt bug. Qt claims it created the OpenGL context and made it the current context without errors. Maybe on Linux it is not correctly checking if the context is valid. It could also be a graphics driver bug in Mesa. If it is the graphics driver it might be fixed by installing an AMD graphics driver.

My only suggestions is to use the current ChimeraX 1.8 which uses a newer version of Qt (version 6.6 instead of 6.4 in your ChimeraX 1.6).
