I am experiencing this lovely problem myself with and without using OptiFine, messing with Minecraft/OptiFine settings, ram allocation, GPU settings, etc; I have 2080 ti and a i7-8700k processor and get this when crossing any chunk in general whether it is in a new or old world. It would be wonderful if 1.14 got this fix since 1.15 doesn't officially come out until "before the holidays".
