issue with chunk rendering

[real jungle]

chunks are not rendering until i come closer to them . The thing is that when i will come close enough to render they keep rendered even if i walk far away . So if chunk already loaded it will keep loaded and wont dissapear but new chunks that if i will not come close there will be empty , plain terrain and nothing else ... Any fix ?

BTW settings doesnt matter . Same thing happens with ultra/low , high loading distance and object quality . Changing meshes doesnt work too . Tried uninstalling and installing . Still nothing .

for example same chunks that i rendered by walking close and going back to pervious location

they keep rendered but i need to get closer to them . It breaks the immersion . Imagine walking in the forest , seeing nothing in front of you and suddently POOF

1 km of forest just appeared from nowhere

tbh this is normal, it's just more obvious because the forest is dense in the mod

well i saw youtube videos and noone had issue like this

and just to make sure i opened vanilla game and it was normal . Only on this modpack disant terrain renders weird.

i have found solution

for some reason this kind of bug appears only if i start afterlife from mod launmcher . I have copied all of the mods and settings from the luncher and pasted it directrly into 7d steam folder and it is working normally.
