Gnome 3.34 freezes when changing tty on Fedora 31

When I change tty (by using CTRL+ALT+F-key ), Gnome freezes. The mouse continues to respond to movements, but mouse and keyboard clicks render nothing. When changing to a terminal tty and executing sudo killall -3 gnome-shell , and then switching back to a graphical tty, the problem is solved sometimes. But if I push and click fast between tty1, tty2 and tty3, the system hangs up and I need to do a hard reset.

Note that I get the same problem when going to tty1 (graphical) and back to tty2 (graphical), as well as when going from tty2 to tty3 (terminal) and back.

In case anyone wonders, the reason I’m using X11 (instead of the defualt Wayland ) is because I had some problems with my multiple screen setup when i started using Fedora on Wayland .

Any ideas?

Setup

x11

journalctl output before hard reset after changing tty, let me know if anything more could be of use
