JDK 7 Mac Port Preview b217 Available

[Frank-Robert Kline]

Actually, I might have figured it out a bit more. The MacBook Pro I see
this on can switch between integrated graphics and the Radeon video card.

By default, in System Preferences > Energy Saver, Automatic Graphics
Switching is enabled by default, causing the Intel integrated graphics to
be selected as active. When the integrated graphics is active, I can
reproduce this issue. When I uncheck Automated Graphics Switching, the
Radeon video card becomes active (you can see which graphics device is
active in System Information) and this issue goes away.

Scott - maybe you could try switching off Automated Graphics Switching in
System Preferences > Energy Saver and see if this issue goes away?
