Walls, fences, glass, slabs and stairs don't seem to be affected anymore, but solid blocks, cobwebs, transparent blocks (such as the beacon, leaves (depending on your graphics) and the honey block seem to be affected) and also the blocks that emit light are. (As of 1.16.1/20w28a)
Removed some screenshots that cannot be reproduced in 18w03b.
