    Description

      There are several scrolling/update bugs, maybe this is related to some of those, but I haven't found a clear duplicate.
      When using the mouse to scroll a code editor on macintosh OSX 10.6.7 against the current qt/qt master some optimization seems to go bad and the y position of some lines gets messed up, so lines of text can be vertically compressed (as they miss single pixel lines or white stripes are visible.
      It seems that always 1-pixel lines are missing(written at the same place?) or at the wrong place.
      A refresh fixes everything, and if one has a special selection (for completion), that gets temporarily redrawn at the correct place.
      Using Qt 4.7.3 the problem disappears.
