pygame OpenGL windows not refreshing on Mac OS X 10.6, Python 2.7

I posted this on the pygame mailing list but maybe someone here will have an answer. I can't be sure whether it's a pygame problem or an SDL problem, really.

Essentially, I have some code that uses PyOpenGL and pygame to render rudimentary animations. It works fine under Linux but for some reason, the pygame windows on my Mac don't refresh unless I click outside the window to "unfocus", at which point they refresh once.

To install SDL and pygame I followed the instructions here. I should note that

  • 2D pygame examples such as pygame.examples.aliens work fine, while 3D ones such as pygame.examples.glcube exhibit the same problem as my own code.
  • PyOpenGL demos work fine, so I'm assuming the problem isn't there.

  • I also see this printed to the console: 

    2010-11-12 00:31:51.328 python[75402:903] *** __NSAutoreleaseNoPool(): 
Object 0x101da6570 of class NSCFData autoreleased with no pool in 
place - just leaking

    Anyone know what that means?

Solution

  • It turns out some sort of OS X driver glitch causes this when I Ctrl+C a pygame-based application, and the only fix is to reboot.
