Missing font on IDE's top toolbar

Hello,

My OS is Fedora Linux 35 with Gnome desktop on wayland.
I downloaded the 64bit linux IDE, extracted the file and run ./arduino from terminal, but the top toolbar is blank, although if I hover the left aria, I can enter the submenu but the font is missing. The only error I from terminal is:
'Gtk-Message: 12:06:19.062: Failed to load module "pk-gtk-module"'

Running Arduino via flatpak works fine. So, something's wrong with the font settings.

What might go wrong?

Thanks in advance...

Hi @AlexTheoto. It sounds like the same problem as reported here:

Someone shared a workaround in that thread.
