Here is a test code (screenshots attached below). Without the labels the left box will be blurred while the right is better (even though it still has slight shadow); when I add labels however their behavior will switch. What I would expect is to have nice sharp lines all the time. Is this Athens issue? Roassal? Pharo? Its ugly both on Linux and Windows. ==================================== | view box1 box2 | view := RTView new. box1 := RTBox new width: 50; height: 51; fillColor: Color transparent; borderColor: Color black; elementOn: '50@51'. view add: box1. box2 := RTBox new width: 51; height: 50; fillColor: Color transparent; borderColor: Color black; elementOn: '51@50'. view add: box2.
