Public bug reported: When launcher is hidden, scrolling or switching in the maximized window "tears" along the vertical line, where the launcher would've ended if it was shown (i.e. (48, 0) - (48, screen height) if the launcher is 48px wide). The easiest way to see is opening two tabs with black and white backgrounds correspondingly and constantly switching between them.
I am not certain, but it looks like redrawing the part "under" the hidden launcher is sometimes delayed for one frame. Neither fullscreen windows nor switching between windows exhibit the problem. The bug did not manifest in Ubuntu 13.10.
