It was 100% reproducible on the computer (10.10) where I found the problem. On this computer (10.11) I cannot reproduce the issue. I can comeback to you when I have access to the 10.10 computer again.
I can still reproduce it on the 10.10 computer, 100% reproducible. I also just updated to 2.0-beta.12.4 which did not help. Is there something I can do to debug the problem?
