So topic says it all. It happens even with original sasc version, and happens on at least OS4 and MORPPHOS. From time to time (i think 20-30% of runs), when dopus5 screen appears, not every icon are visibly on desktop. Some of them are, some of them not. So you need to move by any of window over that empty places, to make them redraws itself. Pretty possible it can be related to how and when backdrop image/icons are drawn, and just some icons draws faster than backdrop.
