Problem description

I've made tickets on Proton's Github, Mesa's Gitlab, and posts on Reddit about issues I've been experiencing that seemingly nobody has been able to reproduce, then I realized that none of them specified they were using the Steam Flatpak like I was.

In certain games, like Far Cry 5 and Jedi: Fallen Order or even Ghost of Tsushima, lighting would shimmer weirdly on characters (mostly their skin) that made them look as if they had vitiligo in certain lighting. My horse in Ghost of Tsushima was glossy, as if covered in sweat. In Ghost of Tsushima and Lords of the Fallen, there was an insane amount of flickering of textures, as well as pop-in that would occur the likes of which has only been seen in modern gaming with Dragon's Dogma 2. Nobody else was experiencing these issues. Switching to the native Steam for Fedora, these issues all disappeared.

Here are the tickets I've created about these issues, as well as some clips of Ghost of Tsushima I'd documented of the pop-in and flickering:

Does this issue reproduce with native Steam

No. Every single issue disappeared. There's no more flickering in Lords of the Fallen, there's no more insanely detrimental pop-in in Ghost of Tsushima, no more vitiligo effect in Jedi: Fallen Order, etc.
