Odd gray and red flicker in The Talos Principle on GK104

Description
When running The Talos Principle[1] on my GK104 under Nouveau, I get two kinds of odd flickering: · some parts of some objects flicker between being bright and less bright · some objects flicker between being "normal" and full-red Although, the "red" flicker does not appear if the game's graphics settings are set to "minimum" – only the bright / less bright flicker happens. It looks fine on proprietary drivers, which probably rules out hardware defects. It also looks fine on an Intel GPU under Mesa.
I recorded a short video[2] in case anyone agrees that one look is better than a thousand words and wants to see it in action.
I recorded an apitrace[3] of it. On nouveau this replays the same way it looks "live". On proprietary drivers it replays "correctly" – the flicker is nonexistent. I did not manage to do the reverse – sadly, an apitrace recorded on proprietary drivers fail to replay at all regardless of what driver is used.
