Seems to be an issue with icaclient running with: xorg-server-common-1.20.0-2-x86_64.pkg.tar.xz xorg-server-1.20.0-2-x86_64.pkg.tar.xz
when starting a session to a windows machine it will consume all resources on your client, it tries to read from a socket at /tmp/.X11-unix/X0 to a insane degree making X unusable. I would guess this is an issue with the icaclient itself and not this package, but thought it would be good to mention here as a headsup. (running with xorg at 1.19.6+13+gd0d1a694f-2-x86_64 works fine for me)
EDIT: someone else has created a post about this in citrix support forum: https://discussions.citrix.com/topic/395450-unusable-after-upgrade-to-xorg-v120/
EDIT2: as sandstorm noted (thank you!) you can workaround this issue with following this guide https://wiki.ubuntuusers.de/Citrix_ICA_Client/#Problembehebung chapter: Probleme mit Seamless Fenstern

If you cannot build because of a missing tar ball or a failed sha256 checksum validation, then the package is most likely outdated and they have removed the old version already. In this case, please click on “Flag package out-of-date”.

Found a fix for "authentication service could not be contacted"
Edit the config file under /home/username/.ICAClient\WFClient.ini and add a new line SSLCiphers=ALL save file and run "killall AuthManagerDaemon ServiceRecord selfservice storebrowse"
Relaunch Citrix and you should be fine
