I’m sure most of us have encountered these bushes that are non-destructible which jiggle, shake, and move your tank if you stand on them. You may not notice if you’re driving, but it becomes very noticeable when you’re aiming or trying to shoot. And many of these bushes are mostly on cap points or in areas that light/medium tanks use as cover. These decorations shake your tank because the game allows them to be destroyed, but allow them to immediately respawn or stand back up. As they respawn (which can happen multiple times a second) they move your tank. Just keep them destructible. No bush is that important to the game.
FIX IT! FIX IT! FIX IT! This has been an issue throughout several major updates.
