I have had the same problem.
Change the display depth from 16 to 32.
(world menu / appearance ... / set display depth ... / 32)

The Squeak comes with display depth set to 16 in default I think.
This normally is enough unless you start playing with colors
on your own. Switching to 32 bit depth "solves" the problems.
