Mavericks Finder window- and shadow-rendering issues-Screenshots

Is anyone having these issues? Is there a solution?

If this is monitored by Apple engineers, please take note:

Mac Desktop with "noise" in place of file icons

Finder windows with black drop-shadows instead of gradient shadows. The black dropshadow moves with the window when the window is moved:

A Firefox window that renders as noise, behind an Excel window

These do not impact my ability to use the Mac, which works fine.

These issues may be related my other post from yesterday - see: https://discussions.apple.com/thread/5503570

Thank you
