I looked at some of the other chunk bugs, but they're old and mine appears differently, like a solid outline of the loaded chunks usually. My game runs slow and chunks often don't load even as I walk up to and past the border of what's loaded (walking into the void creates a falling loop) I've tried f3+a which sometimes helps but some chunks stubbornly still do not load. sometimes opening the menu and waiting 10ish seconds helps them load more often. I've tried lowering several settings and it only helps so much. I have plenty of unused space when I pull up f3 so I don't know why the game struggles so much. I've even woken up in a blacked out, unloaded chunk recently. Frequent crossover with MC-138108, too. Seems to render differently from MC-99333 and MC-5332. Might be similar to MC-17419 but still seems different.
