[Bug 43264] The Witcher 3: Black and red face textures and missing vegetation

Partial workaround (just fixes the red/black face issue, not the missing
vegetation) from: https://www.gamingonlinux.com/forum/topic/2753/post_id=11425

"Open the user.settings file (in Documents/The Witcher 3) search the
[Rendering] section and add MaxTextureSize=64. If this line already exists
replace the number with 64."

Makes the graphics look noticeably worse as well.
