[My interface flashes in rainbow colors 0_0]

I have found the fix. or work around.

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.
