When playing in VR I have a lot of visual bugs and floating textures, all paintings, placed maps, text on signs etc. are not attached to the place they are placed, but float around mid air and follow me when I walk around. 

The same happens to clouds, they are centered on me so if I fly or walk in any direction the clouds move into the same direction. 

last but not least also some lighting issues seem to result out of these flying fragments, it looks like the light level update when you move is resetting and loading from 0 light every 2-3 blocks I travel.
