I just develop on my ubuntu, works fine with wine. I?m not sure if the Settings are the same between Linux/Mac but I could post you what I changed
Would you mind posting your setup (i. e. full kernel version, GPU drivers, etc)?
Construct 2 isn't very stable for me (Ubuntu 13.04, Linux Kernel 3.8, AMD fglrx 12.9) and won't even display the items (sprites, buttons, etc) I place inside it.
