I was having the same problem with the flashing red and green. I have intel hd 4000 prc graphic controller.
In SL,
under preferences> graphics>advanced, uncheck basic shaders. it will fade out the other boxes below but the flashing will stop and the menu and scroll bar colors will go back to normal.
This worked for me. I was running fine without the rainbows, and suddenly they appeared. No clue. This is a work around, but it's far better than the rainblow flashes.
