When I expand a window that is minimized, it doesn't come up smoothly---it's as if it is fighting its way to expand. Jerky. Happens in all programs. Started 3 weeks ago. Need new video card? April 2009 2 X Quad core Macpro. 12 Gig RAM. Video Card = ATI Radeon HD 4870 512 MB.

If mine Radeon 2600 XT can smoothly minimize and restore widowses, 4870 could do 50 at the same time. Video card is not problem here.

in short, it sounds like your drivers are semi-buggered

If GLView reports your card as being your card, it's something else. If it says "Software Renderer" then the drivers didn't load and you are stuck in 2D mode.

Running Snow Leopard 10.6.8?

I believe they broke something because i experience the same on my 4870, + kernel panics.

edit:
The latest Cuda update fixed the problem for me.
