Chromium-based browser behavior

All, I have recently upgraded my users from RedHat 8 to AlmaLinux 9, and have noticed a strange behavior: Chromium-based browsers will just disappear off the desktop while open and user is utilizing sessions. They use both Google Chrome and Microsoft Edge for Linux–both Chromium-based browsers. This does not occur with Firefox. Most users have Dell Precision 7760 laptops, two have Dell Precision 7750 units. Has anyone seen this type of behavior before?

hello

RHEL 9 uses GNOME Shell on Wayland by default, and X11 applications may run through Xwayland.
Since this issue only affects Chromium-based browsers and not Firefox, I would first test with “GNOME on Xorg” or launch Chrome/Edge with --ozone-platform=x11.

Red Hat documentation:
