When going through my nether portal to my base the world loads really slowly and my frames drop down to around 10 from 150, but if I tp or go through an end portal to get home it renders as expected.
It seems to happen more frequently if I've loaded chunks in the Overworld somewhere else then gone through the nether and out somewhere else.
Is this still a concern in the current Minecraft Snapshot 15w44b or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
If so, please force a crash by pressing F3 + C for 10 seconds while in-game and attach the crash report (
[minecraft/crash-reports/crash-<DATE>-client.txt|http://hopper.minecraft.net/help/finding-minecraft-data-folder]) to this ticket.
