I am on the rolling release of Manjaro with Gnome and latest updates and for a while - I think it was the last last major update - I cannot read anything in system dialogs anymore. Also nautilus wont show any text. Installation is more or less stock, using Adwaita in dark mode. Used to work but then after that update text went missing. Tried to dig into how Gnome does stuff, got lost but did not get my text back. Any ideas much appreciated
Its a notebook with an older nvidia quadro K1000M using the 390.157 drivers.
After posting this I happen to find out that this problem bubbled up while I was overseas - there was a solution a few days old that I did not see before posting.
See this post for this solution (others may pop up elsewhere):

add the following lines to /etc/environment and reboot
