When I run the game Deadlight with Proton or Wine, I get strange artefacts, as you can see on this screenshot: https://i.imgur.com/mdEnFQX.jpg
I’m not the only one with this problem, as it gets reported by other Nvidia users on the Proton Github:
It seems that users with GPUs from different vendors are not affected, as on ProtonDB all platinum reports are by users using an AMD GPU.
OS: Linux Mint 19.1
