I first experience it on my 1.17 single player world, but then it was only in the nether. Came 1.18 it affected both dimensions. I tried creating new world thinking it was an old world issue,but apparently new world too started to lag. tried to break blocks but no breaking particle but soon it catch up and break. Doors,animals, piston,fence gate started to lag and desync and froze. Flying was unable with an elytra. I noticed the player also lags behind. monster also atacking/tracking me where i have walk before. If it's pending tick buildup then i tried exiting and reloading the world but non avail,it still lags behind.
Happened on phone with mali gpu (mediatek 930), and snapdragon 732g (2.3ghz).
