I have laptop and a desktop, both running Fedora 32 Workstation, Gnome 3.36 and mythfrontend version fixes/31. If I log in using Xorg, mythfrontend starts and runs as expected. Under Wayland, mythfrontend does not open its screen and the system remains at the Gnome desktop. Eventually the system tells me that mythfrontend is no responding and asks if I want to kill it. After starting mythfrontend, I cannot switch to or interact with the Gnome desktop or any open window using the mouse - the mouse pointer moves, but nothing reacts to it. The only way I can change focus away from the hidden mythfrontend process is to alt-tab my way through the running programs and select an open window of a different program. Mythfrontend's icon does show up as I alt-tab. Both the desktop and laptop use Intel integrated graphics.
Running mythfrontend from the command line on the desktop computer produces the following output that appears to be relevant to my problem:
Code: Select all
"Display: Requesting EGL for 'Mesa Project, 1.4'"
