[Bug 1316092] [NEW] When the launcher is hidden, tearing occurs when scrolling/switching contents inside one window

  Thread Previous • Date Previous • • Thread Next 
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.
