Flickering after embedding H5P in Moodle
Today I embedded H5P "fill in the blanks" in a page-resource and a lesson-resource in Moodle. After that, both the page and the lesson started to flicker on all my devices. The page and the lesson also contain other embedded H5P code (though in the lesson not on the same content page). The Moodle-activity "stealth mode" (activity invisible, but accessible) was activated at first, deactivated at the end, but the flickering continued.
It seems like a programming error. Does anyone know what to do?
My Moodle-version: 3.5.3
My H5P-version: 1.14
Laptop (Ubuntu), iPhone and iPad
Firefox and Safari
Fill in the blanks (perhaps also others)
PHP seems to be fine.
Many thanks for helping out.
PS I have a video showing the flickering, but I can't upload it as MP4 is not allowed here.
