Fedora 33 to 34 upgrade issues

[tydeman]

PineBook Pro still has Manjaro on its internal "disk".
I have Fedora 33 installed on a 64GB uSD card 
(that mostly runs OK -- Shutdown does not turn machine off)

Today, I followed these instructions to upgrade from Fedora 33 to 34.
It appeared to work OK.

How to upgrade from 33 to 34 (in place):
  NOTE:  Some of these steps take many minutes (appears system is hung)
su -
dnf --refresh upgrade
reboot
dnf install dnf-plugin-system-upgrade --best
dnf system-upgrade download --refresh --releasever=34
    ... takes a long time to download 3399 packages
dnf system-upgrade reboot
    ... takes a long time to install 3399 packages
su -
rpm --rebuilddb
dnf distro-sync --setopt=deltarpm=0
dnf install rpmconf
rpmconf -a

https://docs.fedoraproject.org/en-US/qui...m-upgrade/
    ... above plus these:
su -
dnf update
dnf repoquery --unsatisfied
dnf repoquery --duplicates
dnf list extras


That last command lists several packages, but the one I am worried about is:
  pinebook-pro-fixes.aarch64
and perhaps:
  ap6256-firmware.aarch64

The Dolphin file manager works OK.
System settings works OK.

But, firefox has issues.
  It starts and has a window with a title, but the main window is transparent;
  in that I see the desktop
Also, emacs has issues.
  Starting it from the desktop icon acts the same as firefox -- transparent window.

From a Konsole, starting either "emacs &" or "firefox &", I see warning from Gtk
that "window_decorations.css" is missing.
