Symptoms
This is my first entry for issues due to being new.
STO had a recent update as of the 25th Jan 2022. Since then, the screen to enter my credentials suddenly ends to desktop. I have tried various other Proton drivers (ones seen on ProtonDb and random via Steam) and the same screen drop occurs every time. Now I can launch the game with the .exe but control in-game is not as good as it is via Steam/Proton. I have been using Proton Experimental since October 2021 and I did try the other 2 to see any effect. The same issue occurs. I have updated Proton DB with my entry. Thank you.
