Most Console errors can be safely ignored.
When I am having performance problems .. and no reply from tech support ... I find it disturbing.
Generally speaking the Console normally contains warnings of potential problems such as deprecated function calls, methods declared in multiple frameworks, etc. If they turn from potential problems into actual problems, you'll definitely know about it because the app will crash.
This warning does not look like it has anything to do with performance. But having said that, you should still report these errors to Adobe so that they can amend the code to prevent a potential crash.
My app PP did crash! Several times! I am very afraid that my work will be erased .. I'm always in the middle of a project and cant afford these problems.
Oh .. and I did send the crash report(s) to Adobe. I never get a reply that they were recieved.
They ask for my email but never send a confirmation that they got it. Why?
Do you get confirmations?
