I have been running everything under Wayland for several months. Today, I noticed the updates included revised packages for some mesa-egl stuff, so I decided to re-verify that things were still running under native Wayland. What I discovered is that they are not.
First, I surfed to about:support in Firefox. It showed that it is now using GLX, which indicates it is running under XWayland. Bad.
Then, I ran looking glass to make sure. Every running window (Firefox and two for Gnome terminal) is running under XWayland. Very bad.
I have not done anything overt to invoke XWayland in Fedora 30. How do I correct this?
