Has anyone seen this problem? After some 5 days after a successful installation of Mint 14 Cinnamon, now when I boot up, the bitmaps of the standard icons in the menu are scrambled. I made no changes to desktop preferences, other than moving the menu to the top of the screen. And I added a second monitor (should have no effect).
The tool tips still work, and so does clicking on the icon. Note the application icons in the menu bar still appear correctly.

The four icons on the right are also scrambled. But, if I hover the mouse of them, they revert to their proper display (not the case with the left icons).
