Hi Giuseppe, thanks for the help, this is what I think too. It's hard to known why sometime it fails but the sample is kept and sometime it fails and the sample is back to 1. This will be hard to detect and make decent fall back or warning. I will try on the real machine as main Linux OS.
Thanks for the help,

My gut feeling is that you simply don't have working MSAA in a VM. I
don't think the Shape module supports any other form of AA when rendered
through OpenGL (but I might be wrong on this).
