Hey guys,
I've been having this issue on my iMac.
Ireal pro opens and runs, but the window is completely transparent.
I can click inside the window and a tune plays. But no visual

I am running Yosemite DP5. But I real has worked for the past betas and my brother is also running DP 5 and iRP works on his MacBook.
I have tried deleted and reinstalling several times to no avail.

Please advise, have you folks seen this before? Is this a Yosemite DP 5 bug? What should I do?

Fortunately iRP works ok on ios8 except for the audio bus bug.
