Running in the Ext JS 5 nightly build of the 28th (and probably earlier) if you have a grid with a locked column and there is a vertical scroll bar, when you scroll the unlocked contents fully to the left (contents go left, scroll bar moves to the right), the vertical lines will also shift to the left equivalent to the width of the scroll bar. As a result, the lines for the column headers no longer line up with the rest of the data. Tested on Windows 7 with latest Chrome and Firefox.
