Hey Oscar,

my option was if the app even won't start with your old preferences...

But this looks more like the old transparency bug which is simply a misbehavior of values.. Try to adjust the transparency of the mix to 1.00 (If i remind right)..
This is a known bug in the keystone option within mixes, could also happen to your option..

I will have a look on thursday into the settings for the exact value, but this could solve your problems..

Best

Rolf
