Bug 1: occlusion setting makes trees flicker, this is solvable by disabling screen space occlusion
Bug 2: as seen in screenshots and video: https://vimeo.com/1081113572?share=copy#t=0
HD grass bushes turn into white low-resolution things in the distance and flicker heavily. In some areas this is very noticeable and annoying
I don't think these grass bushes are affected by grass setting either, so they probably count as bushes.
Additional suggestion: allow us to completely disable grass
