--- Comment #15 from Bernat Arlandis berarma@hotmail.com --- Sorry, I'm late but I can confirm the new patch works equally well on Proton 5.0-8 (I forgot to git pull). Now I'm building it for 5.0-9 but I guess it'll be fine too.
Thank you again. Really appreciate the time you're putting into this issue.
