Description Dirk Griesbach 2014-08-08 08:16:22 UTC 
In dual monitor setup, if one of the two is rotated, moving the cursor from the rotated screen to the normal screen shows two cursors, one active cursor with the correct orientation and a second cursor with the orientation of the rotated screen. Only one cursor is shown, if the cursor is moved from the normal screen to the rotated one. The second, stray cursor is a bit shy: it wouldn't show on a screenshot made with gimp and does vanish if the real cursor is updated (e.g. on window boarders).

    sna: Restore the clear before pwriting the cursor
    
    Along the legacy phys cursor path, we use a common scratch buffer. As
    this is global, we need to be careful not to trust the cursor local
    dirty tracking and be sure to clear the image before uploading.
