I do not have much experience debugging OpenGL stuff either, but from the description I would say that this could be a bug in Cura, or it could be a bug in the OpenGL implementation for AMD VEGAM, whatever that is. Perhaps it is an idea to identify the package being used by X.org for this card, and pass the bug report over to them for comments is a way forward? -- Happy hacking Petter Reinholdtsen
