hello, I'm testing a custom actor made with cogl, I apply the scale and
opacity behaviour, but with the opacity behaviour does not work (nothing is
showed), but instead of use a custom texture I use a clutter.Rectangle and
it works... so maybe is a bug or I'm doing something wrog.. anyone can test
it?
thks!
