[Bf-committers] OS X GL troubleshooting help

[Douglas Bischoff]

Hello:

Doing some work today in a compile from yesterday's CVS, and noticed 
some odd behavior which might help explain the crazy screen behavior on 
OS X.

When doing an F12 render, the render window looks fine, while the 
background (the rest of Blender) goes haywire with random pixels... 
which appear to be from the system "wallpaper" by the way... in a 
repeating pattern.

I tried dragging the render window around, and discovered that behind 
it, and where the system was drawing a drop shadow, the screen redrew 
itself just fine... showing the remaining Blender interface nicely.

A second drag over the same area... and it went back to the crazy 
patterns!

Sounds like a swapbuffer somewhere?

Hope this helps,
