Native wayland Chromium broken after latest update

[pizzadude]

On Fedora 40 KDE, the latest update to the Chromium flatpak broke native wayland, it just launches a transparent window where my cursor trails everywhere like the old Windows XP days. I had to switch the "ozone" back to default in another chromium build and copy my config back.

same issue on Fedora 39 using flatpak image, rolled back to previous version:

sudo flatpak update --commit=d8cc53624b3a8569d93af57ff587bfdb316cf295802a7ea5374fea22ac3ba2fc org.chromium.Chromium

This is an upstream bug and specifically applies if you set the "Preferred Ozone platform" / ozone-platform-hint option. You should be able to run Chromium with --ozone-platform=wayland to work around it.

If you're specifically using the --ozone-platform-hint command-line option (i.e. not setting in chrome://flags), please try #386, it may fix that issue.
