Workaround: If you are stuck Chromium using native Wayland support, you can reset it with the following steps:
1. Log out GNOME on Wayland session and log in with Gnome on Xorg session. 2. Launch Chromium. 3. Enter chrome://flags into URL bar and reset the setting “Preferred Ozone platform” to “Default”. 4. Log out and log in again with Wayland session. Regards Stephan
