ATTEMPTED BUG FIX
We've become aware of some games on Steam Deck and Mac appearing with super-saturated colors. We believe this may have been caused by some HDR processing in our game engine. We do not use HDR specifically and have disabled the settings that may have been led to this problem. This is our best guess at this time, as we were not able to reproduce this issue on our side.
Thanks to our community for reporting this to us!
