Minimap and large map glitching out and updating a lot

[TrashCaster]

This happens in the Nether above bedrock on my server. I haven't seen this happen in the overworld. Using the new 1.16.2 version of Unlimited.

Here is my config:

{ "waypoints_world_render": "true", "advanced_info": "true", "show_offhand": "true", "show_waypoints": "true", "map_offset": "16", "skin_scale": "2.0", "map_visible": "false", "show_in_chat": "true", "items_position": "MIDDLE_LEFT", "show_chest": "true", "current_skin": "0", "big_map_size": "256", "purge_amount": "1500", "show_slime": "true", "map_info": "true", "terrain_strength": "2", "max_render_dist": "1000", "show_player_heads": "true", "info_position": "MIDDLE_RIGHT", "alternate_color_render": "true", "arrow_size": "6", "chunk_level_update_interval": "3000", "entity_icon_size": "2", "rotate_map": "false", "force_map_update": "false", "show_legs": "true", "simple_direction_arrow": "false", "draw_chunk_grid": "true", "show_entities": "true", "map_size": "96", "worldmap_icon_size": "8", "show_feet": "true", "use_skins": "true", "purge_delay": "60", "render_animation": "true", "show_time": "false", "show_entity_heads": "true", "show_icons_outline": "false", "map_position": "TOP_RIGHT", "show_topography": "false", "water_tint": "true", "chunk_update_interval": "1000", "hide_plants": "true", "show_big_map": "false", "render_light_beam": "true", "min_render_dist": "1", "show_hostile": "true", "hide_water": "false", "show_FPS": "true", "arrow_type": "PLAYER_HEAD", "map_brightness": "0", "waypoints_tracking": "true", "show_loaded_chunks": "false", "show_position": "true", "entity_outline_size": "1", "show_light": "true", "show_terrain": "true", "map_scale": "2.0", "show_head": "true", "show_mainhand": "true", "texture_filter": "false", "show_player_names": "true", "render_entity_model": "false", "show_players": "true", "entity_model_size": "2", "move_effects": "true", "show_items": "false", "show_caves": "false", "show_creatures": "true", "map_saturation": "0", "render_markers": "true", "show_biome": "true", "show_effect_timers": "true" }

This didn't happen in the 1.16.1 version though. As to why it would suddenly stop functioning correctly in the next version, I don't know.
