Description
Removing many blocks (flattening) causes severe performance drops. Realms: periodic lag spikes; Local: feels like constant slow motion. Standing still sometimes restores smoothness after a few seconds, yet delay can still appear when standing still. Framerate graph in video shows periodic spikes. Video + world file linked. MCPE-171807 visible but unrelated. Happens on both small and large edits (worse with large), and is intense on Realms.
Reproduce
Structure Block → select 64×200×64 air, Save.
Place at Y≈64, Load.
Repeat to make a huge flat area.
Walk, fly, or stand still there.
Expected
Edited chunks should not cause major slowdown or delay.
Observed
Game enters heavy slow-motion with high delay in edited areas

The graph in the video is very low quality, so I took two screenshots. In the first one, you can see how the framerate drops periodically, making the game feel like it’s in slow motion, then normal speed, then slow motion again, and so on. In the second one, you can see what it looks like when you stop moving.
The video has very low quality, but I still hope u can see the graph! And u can still slightly see the periodically happening slow-motion effect this bug causes!
On the Realm, I removed more blocks from more chunks, so there is more lag than in the world I uploaded here. But still, also in the world I uploaded, u can most likely experience it
