Assasin's Creed Valhalla - logs spammed with Invalid plane index 0 for format 0.

[Lifeismana]

PROTON_LOG=1 's logs are getting spammed with the following warning:
warn:vkd3d-proton:vk_image_aspect_flags_from_d3d12: Invalid plane index 0 for format 0.
a 1.5 hour game session made the log file 5GB, so i assume that warning is happening on every frame

Software information

Assasin's Creed Valhalla
It starts as soon as the game launches
Disabling ubisoft's overlay doesn't stop that, neither does disabling MangoHud

Since that log spam doesn't happen with Skull & bones which uses the same engine, i'd assume this is a game specific issue

Game is launched with PROTON_LOG=1 %command%
