So, i have come across a bug in 1.18 where it seems to be black but for a split second it shows a frame and then it goes black again... it does this every time i tab out.

I've been getting this same thing happening to me too. It's really triggering my photosensitivity (Don't worry I don't get seizures, it just gives me a splitting headache)

might be caused by figura, but not sure

Very strange! Does it still happen with just Dynamic FPS (and Fabric API)?

nope, just when figura is installed alongside

Edit: At least for me

fixed in figura :)
