I'm using a Raspberry Pi for a Digital Signage project for university.

I have a small issue with a hover hint box (I don't know the correct name) showing when Chromium plays YouTube Fullscreen.

I had to change some flags to get media working:

  • GPU Rasterization Override
  • Override software rendering list

This is the command that runs at startup to launch Chromium:

/usr/bin/chromium-browser --kiosk --disable-restore-session-state --autoplay-policy=no-user-gesture-required http://localhost/wordpress/index.php/foyer/presentation/

Autoplay-policy was what fixed videos not playing automatically.

YouTube Video player hover message on Chromium on Pi OS. https://i.sstatic.net/5Rzuq.jpg

I'm hazarding a guess that the cursor defaults to the middle of the screen and that's why it's appearing, as moving the mouse makes it dissapear.

Really appreciate any help given. TIA

I ended up fixing this by installing unclutter and incorporating this command into my .sh file:

/usr/bin/unclutter -idle 5 -grab -root
