…lipse-windowbuilder#1524 The way a Swing component is moved on Linux is via a request to the window manager, which is then processed asynchronously. Because of this, it might happen that the relative location of two widgets is calculated while one is being moved, leading to wildly inaccurate results. To reduce the likelihood of this happening, we wait until the offset remains the same two times in a row, which makes it very likely that the move as completed. Closes eclipse-windowbuilder#1524
