Multiple issues since last update

Morning everyone,

I've experienced a problem since I updated the game earlier today: the colors in game are very vivid, which is not such a problem but also the Shop & Menu windows are huge, and I can no longer change their size. Furthermore, switching to desktop with Alt+Tab now takes a ~3 second black screen, while it was quite instantaneous yesterday.

Anyone experiencing the same? Anyone would know why this happens? Thank you.
