2D track shadows fail to render

I've updated and rolled back Vegas 11 versions and AMD drivers, and cannot pinpoint this issue. It just arose, was no problem a couple of days ago.

Have several tracks with 2D shadows. They appear fine in the preview window when the file is first open. Short test segments will render these shadows.

But the shadows fail to render when the designated render length is longer, even early into the render, doesn't matter to what format, mp4 or image sequence.

And when this happens, after the render or aborted render, the shadows disappear from the preview window in every instance where they are used. They are still present in the track settings.

I rolled back the system to the AMD driver, Catalyst 12.3, where everything worked before. No improvement. It happened while I was in the previous build of Vegas, and updating to the latest build did not change things.

Win7, Vegas 11 Pro, Radeon 5570, i7 processor, 8GB RAM.

Fixed it. I just thought I had rolled back my driver by installing an earlier version. When I rolled back through the device manager, that restored previous 2D track shadow functionality in Vegas 11 Pro. Must be an openGL change.

Looking forward to getting an nVidia card. AMD driver updates are unreliable. I learned from this to never, ever update a GPU driver while an important project is in progress.

I should add that the driver update that caused dysfunction came with Catalyst 12.4. I rolled back to a driver with a March date.

It's all drivers can cause issues, not necessary one specific company. I save all the drivers versions I download so if one doesn't work I can fallback to the others but I normally don't update unless I need to.

I've had driver issues also, using a 560ti. Not specifically with 2d shadows, but with the preview/renders getting stuck on a frame. For me nothing after Nvidia driver 280.26 has been stable in Vegas pro. So it's not just ATI cards suffering. It should also be noted that I haven't tried later drivers on 682/683 yet.
