Hello,

I was running REW on a 13" Macbook Air successfully (OSX 10.9.4). Today I installed REW on a brand new 13" Macbook Pro Retina (same OSX version). At first sight REW runs fine, but as soon as a graph is displayed (RTA, SPL&Phase, ...) the app becomes very, very slow.

I suspected the 'Retina' and changed the screen settings to a lower resolution. It didn't help.
I also made sure to run the lastest Java version (Version 7 Update 65).

Anyone experiencing the same problem?

Thank you,

Serge Nelissen

Are you running the latest REW beta version? I have seen complaints on a Java forum about image handling under OS X for Java 7 and Java 8 which could be the cause (it seems hardware acceleration is not being used when it should be).

Yes, the latest version (I checked) which is the same version on the Macbook Air where everything runs fine.
Oh, one thing I forgot to tell: in Activity Monitor I could see REW is taking 50% processor time!

Hello John,

I just realised you are the developer of REW

Tell me what to do and how I can help to isolate the cause of this problem.

It seems most likely to be a Java runtime bug in the handling of buffered images for retina displays, something very similar has been reported but likely won't appear before JRE8u20. I may be able to work around it by using a different image type, I'll look at that but it probably won't be for the next beta, more likely the one after.

No need to hurry for me, I can still use the Macbook Air.

Hi everyone. I seem to be experiencing the same problem on my MacBook pro retina. Everything works fine until a graph is displayed, then it becomes choppy and unresponsive. I am also running Windows 7 under Parallels on the same machine so will try there as well to see if it is any better.

I have exactly the same problem with a 13" Macbook Pro Retina. The latency of REW is about 1 to 3 seconds for all kind of commands made with or without the mouse.
