I have an OLED monitor and configured X to use 10 bit color depth
as described here:

https://linuxreviews.org/HOWTO_enable_10-bit_color_on_Linux

Using Gnome on Wayland I never experienced any problems with this,
but I switched to Stumpwm and can't start Emacs from
there if color depth is configured to 10 bit. I included the error
message printed by Emacs as an attachment. My system
is Arch and all programs were just upgraded. The bug persists if I
don't load the init file.
