This weird green blot/blur showed up when I hit the materials overlay while I was looking if there was co2 in my base.
It was gone after a save/load game though.
I couldn't find the output_log.txt file
Steps to Reproduce
I have saved the game just after that happened, I'll attach it here if needed, although it didn't show up again when I reloaded.
