BotW runes cause visual artifacts on Link (Linux/RADV)

[DonutWrecker]

Current Behavior

Edit: I've just realized it's not only caused by the runes, but certain camera angles cause a similar artifacting as well.

I've been seeing flickering visual artifacts on Link recently when I'm using runes, i.e. Magnesis, Stasis, Cryonis. I have cleared both the Cemu shaderCache and the mesa_shader_cache, but it didn't work. I'm using the latest available kernel with the latest available Mesa drivers. I haven't changed any settings in the graphic packs since I've started playing, and I haven't come across such artifacting until recently. I suspect it's caused by the latest Mesa drivers.
