The graphics glitch/flash across the screen when I'm in the museum. It seems to have something to do with the workshop-thing/the flashes/the effects around the exhibits like the iceflakes around the frozen exhibits. When I started the second museum there was no problems until I started letting guests in and using the workshop. There is no issue in the menus/the expedition screen etc. I tried lowering the settings which didn't make a difference. I also tried disabling lights/shadow and the other individual settings, which also didn't help
