About this bug when i play multiplayer and singleplayer, the chunks seems stopped to loa, to made chunks load i should place or break any types of block or it will remain invisible. even walking starts to stop loading and i should place or break a block just to load the chunk. it even affects multiplayer and singleplayer.

Edit: Here is two screenshots given as an example, taken on 1.16.2 but still happening on 1.16.3

New Edit: captured on mltiplayer 1.16.3, finding another example of this on singleplayer
multiplayer chunk doesnt load on 1.16.3, singleplayer screenshotis coming
