Broken geometry & extreme pop-in (e.g. trees, foliage) similar to https://www.reddit.com/r/linux_gaming/comments/1twhu7p/onimusha_way_of_the_sword_graphic_bug_tree/ however they are using a nvidia graphics card so it's probably not driver-related.

Start by reviewing the attached steam-3974650.log and the linked system information report, then compare them with the reproduction video and described geometry and foliage pop-in. Use the game's simple reproduction case to verify whether rendering improves; done means the broken geometry and extreme pop-in are resolved for Onimusha: Way of the Sword DEMO under Proton Experimental.
