I'm using version 5.0.2, I don't know if what I'm going to report fits as a scid bug, but when in doubt I decided to comment. In the menu in the option Play - Play on FICS - in the FICS configuration box there is the premove option I always left this option activated in all versions of scid that I used until today, but the premove never worked for me. Unfortunately I am unable to play blitz and bullet, without premove it is impossible to have any chance in the quick game. This problem is just me, does it work for anyone else? Maybe it's some dependency I have to install on linux? Timeseal has nothing to do with that, right? Thank you for your attention.
