Could you please clear the pixel buffer when selecting a new pattern.
Right now, leftover-content of the previous pattern persist when switching between certain gobos.
Also, please reset the "internal" rotation index of the pattern when selecting a new pattern.
Not only the gobo rotation index but also the internal-effect-rotation index.
When I want 2 rotating patterns with a 90 degrees shift, cuelux seems to remember an incremental rotation,when switching between patterns, if that makes any sense.
