Minecraft pixel/ texture issue problem

Since the latest update, when adding mods to our Realms world, certain pixels on the edge of textures from vanilla or modded blocks change size, appearing sometimes as half size of a usual pixel or 2/3 the size of a normal Minecraft texture pixel.

We have tested with multiple unrelated mods and can confirm it still happens even with whole different sets of mods, so it isn't a one specific mod we have. It's also important to note we have no texture packs on which would affect usual Minecraft vanilla textures and only use Vibrant Visuals (from Minecraft)

This bug has only started since the latest 26.3 update and nothing of the sort ever happened before this.
