In one of my custom interactive slides i am using a transparent button to disable the activity buttons on the background layer once user has click them all.
When navigating back and forth in the published module users some time see a blue patch (the transparent button i used) for a quick second and disappears. It happens more often on the LMS rather than on standalone.
Has anyone encountered the same? Any work arounds?
I have attached a sample of my interactive slide for reference.
