Can confirm 18 takes about 2 minutes to load on ubuntu.
17 was fine. Never really tried 18 as it have been doing other things. Ie ircd web and other server related things.
Took about 30s to open about describe with no info on version. So I believe its 18 lol
My theme could have changed text as I hate white backgrounds. Due to it burns my eyes.
Just installed 19 and taking minutes to open also.
So something changed. Possibly the compiler and gathering everything.
