KDE 2.3.2, KDE 3.3, Blender 2.34 == Trouble???

["Bob Tilley (AT&T)" <bobt@cocoa.tybrin.com>]

I use Blender 2.34 on a Debian unstable box with KDE and apt-get update nightly.

Blender recently began display strange, "blocky" behavior.  The cursor in Blender would not smoothly transition as I moved the mouse.  Inverted blocks of color would follow the cursor on the screen and when clicking through menus.

Blender is useless in this mode.

I never had problems previously, however I recently updated KDE from 2.3.2 to 3.3 and believe the cause to be a problem in the underlying libraries.  Perhaps a different window manager will solve my problem.  I am cross-posting this to debian-kde and Elysiun.

Any ideas are most appreciated,
Bob
