Staying for a small period of time in areas cause chunks to stop loading in roughly 5-10 away from the player (me). In flight mode (creative) dropping into these unloaded chunks player falls and start to glitch fall (moving up and down constantly). Staying at my base and the chunks there have loaded, but when travelling and later returning the chunks at my base are also at this glitch/unloaded state with mobs glitching. Mobs in the chunks are visible, but you cannot interact with them and they also vibrate in the spinning axis.

It ether stops loading chunks properly in the specific range or stops loading any chunks further.

For now the workaround is to simply relog, but the problem occurs soon again.
