I tried to find how to enable X11 on Fedora or check what I am using (X11 or wayland), so, it seems like the whole time on my laptop I was using X11. Maybe it was because of my cards (Intel + Nvidia).
Now I configured system to finally use Wayland (I hope!), so ``` $ echo $XDG_SESSION_TYPE wayland ``` And... No freezes in Geany!
So, summary: 1) Fedora 33 + **X11** = freezes in the Geany 2) Fedora 33 + **Wayland** = smooth running of the Geany
I am sorry to confuse you.
