I've just installed the current custom bundle 15 EAP on OSX for the first time and I'm having major problems. Is the custom bundle OK on Mavericks? IDEA is causing major system instability and locking up the system for minutes at a time. The screen is full of rendering issues and flickers constantly, it shows as utterly garbled. At first it appeared to be working, took a long time to index and then complained about the spring config mappings. I'd just started to modify and remap some of those and everything locked up and went crazy. Evenutally it allowed me to quit, but restarting the EAP causes the same problems all over again. I'm not short of threaddumps it seems.
