Game does this visual bug lol

I think I have the same visual glitch, after the full cycle passed it disappears. MacOS, M1

Could you try the following and let me know if it fixes it.

1) In Steam, Right-click on ONI -> Properties

2) Under the General Tab, choose "Set Launch Options..."

3) In the text field, add "-force-glcore" -> Click OK

It fixed the issue for me, only one thing I noticed, that it changes slightly the colours.

Without the "-force-glcore" vs with "-force-glcore":

can it be that bottom image colors are right one because off radiation?

At first I thought so too, but I made the screenshot, saved/quit the game and removed the "-force-glcore" from the game settings. Then the colours went back to normal.

There are some compatibility issues with certain Mac hardware configurations that need to be investigated. Using glcore tends to produce the least amount of issues but as you found with the biome tinting it's not without side effects. Here's a link to the stickied post.
