I can reproduce this on LXDE. You need the task bar to have white background and also set it to auto-hide. When launching an application, the task bar must be hidden, otherwise the icon will be displayed correctly. While this may be a bug in LXDE, for some reason it only affects applications which use Qt 5. Application which use Qt 4 or GTK are not affected.
