The problem is probably due to the test on-screen color patches that are rendered in a full screen window but have a trasparent layer applied to them instead of being opaque as expected (see atteched screenshot). This does not appear to be an argyll problem as the calibration with the same setup can be performed sussessfully installing and using DisplayCAL app that also uses argyll. The bug is also present in the X session.
