Some items disappear on wall only

all presets appear corrupt on my wall but in the editor and preview it looks OK

Please ensure that you have "background scrolling" enabled in your Launcher settings, for example, in Nova, you can find this in "Settings -> Desktop -> Wallpaper Scrolling". Then ensure that the image you set as background is larger then your screen (if you cropped it to screen size it wont scroll because there is nothing to scroll). Finally ensure that the number of screens in your launcher have the same count as the ones on the preset you are using.
