Framebuffer incomplete

[workingDog]

I often get this error when I have a few airspaces displayed, causing WWJ to crash/freeze.
I zoom in and out a number of times at close range, sometimes going inside the airspace, then after a while it just crashes.
I cannot see how to resolve this issue. Any ideas on how to fix this?

Could you post a screen shot of your CPU and memory usage.

Optimize, optimize, optimize.

Can you create a small example program that exhibits the problem and post that?
