Bug Description
Compiz causes noticeable vertical tearing (NOT horizontal tearing) inside windows. It appears that there's a column ~450 pixels wide near the left side of the screen that is redrawn at a slightly different time. I first noticed this when scrolling and switching tabs in Chrome or Firefox. It's most visible when rapidly switching between tabs with different background colours.
Enabling the "force full screen redraws (buffer swap) on repaint" workaround in CCSM fixes the issue completely.
