I have an armv7 raspberry pi 3B+ running Kodi and Wireguard, which I updated today:

After that, I rebooted the machine and Kodi was not shown on the TV screen anymore. Looking at kodi.service, I found that it had failed:

I've then downgraded the installed packages using the pacman cache, except libgcrypt which I couldn't find in pacman cache directory:

After that, I rebooted again the machine, and kodi.service was able to work again:
$this->bbcode_second_pass_code('', '
$ systemctl status kodi.service

It seems that everything comes down to the following service command:
$this->bbcode_second_pass_code('', '
/usr/bin/fbset -g 4 2 4 2 32
')
This command shows no output on kernel 5.4.72-1-ARCH, but fails with the following error on kernel 5.4.73-1-ARCH:
$this->bbcode_second_pass_code('', '
ioctl FBIOPUT_VSCREENINFO: Invalid argument
')
Any idea how to be able to fix this in the newer kernel? Any help on how to debug this is appreciated, thanks
UPDATE (2020-10-30): removing the fbset command from the kodi.service file seems to fix Kodi, as said by someone in the #archlinux-arm IRC channel on Freenode. But anyway, is there a reason to have that command there modifying the framebuffer? Is the removal of the command the proper way to fix it?
