I wanted to check the status of the OpenGL renderer this morning, so I’ve updated to the tip.
Here is what I’m seing on an iMac with 10.7 using the Juce Demo

Looks like some redraw issue in inactive part as I was trying the animated version and as soon as the drawing zoom to fill the whole display, the header gets dirty.
FWIW, this do not happen on Windows.
Hope this helps.
