I tried to understand this issue and now think that the NSView extension 
methods in Frameworks/Cynthiune/NSViewExtensions.m are causing this 
problem. There the -centerViewHorizontally method exactly centres the 
view, which may place the view between pixels. A call to -centerScanRect 
(on the super view!) should resolve the issue.

A similar problem arises in the method 
[PreferencesController-setBundleView:], here both directions may 
getplaced incorrectly and of course, there may be plenty of other hidden 
places where this goes wrong in Cynthiune code.
