I don’t know if this is caused by my instalation of cygwin or something else. When my character tries to sleep the time passes a bit slow.
So before he gets a full night of sleep it takes about 60 seconds to pass in real time. Before trying the newest experimental version sleeping was a lot faster - 10 - 15 seconds.
Is Insomniac trait has to do something with this?
Check your CPU usage, I’ve noticed my game’s Sleep (Crafting, Waiting, any period of time where you’re locked out and “doing something”) times increase whenever my CPU usage is high… Piece of crap laptop…
CPU usage is up to 50% when reading so it’s not that bad 
I don’t think isomniac has anything to do with it, that just keeps you from falling asleep in the first place.
I’ve noticed the game stutters a bit while sleeping (but not while reading or waiting) and it has been so for some time (around 0.6). Might be my laptop.
