Description
When using JEI to look up recipes for FD (And sometimes by interacting with FD tile entities, especially the cooking pot) the UI will be blacked out or have the default missing texture purple and black, when using any additional resource packs. This includes the minecraft developer art pack, the xisumavoid vanilla tweaks packs (which only affect sounds and held item position in my pack), and packs that only adjust json models

After interacting with the missing UI, other textures may vanish. In my experience, this has included tiles or blocks that take up more than one block space (Beds, tall grass, tall flowers, to name a few), as well as item textures for dropped items and mobs.

Last, continuing to play after this point can potentially result in a crash, while attempting to re-order resource packs will cause a crash.

Of note: This was not occurring until I installed FD as of 6/4/21, removing it does fix the issues mentioned above

Steps to reproduce:
Install FD, use a resource pack other than default, wait a while, check a recipe in JEI or interact with an FD UI of any kind. Afterwards, enjoy the potential missing textures and crashes.

Expected behavior:
UI appears as intended while using additional resource packs, does not cause textures to go invisible, does not cause a crash.

Apologies for the long delay, things got very busy for a bit.

I went over the steps you requested today, the problems kept appearing even in just FD + JEI + OF. It seems to have been an OptiFine issue entirely, as it did not occur without OF.

However, with some further testing, it seems that updating from OptiFine HD U G7 to HD U G8, the issues have been fixed entirely from their side. I will keep playing and testing for a bit to make sure it stays functional, and will reopen if it happens again.

Running through your game's logs; at first glance, it seems to be OptiFine tampering with GUI render methods. Something about it seems to be trying to access client render classes in the server thread, or something similar.

Please try running the following tests:

• Disable your shader and run through your steps again;
• Remove OptiFine from your pack and try again.

Right, so, I had to make a fresh instance because that pack will now crash with optifine removed. But, now, with the same mods without the shader, it does the same thing. Same mods with no shader and no optifine, the missing UI issue is fixed, but, uh...

This happens now when adjusting resource packs. Relogging fixes it, until you move things again. Removing FD also fixes this particular weirdness.

Further update: Apparently removing, then re-adding Optifine and the shader again has fixed this. It's no longer log spamming, the UIs are functioning as intended, and there's no textures disappearing.

Oof, that's a weird bug. This new log also doesn't seem to report anything unusual. 😥

Optifine issues are usually very hard to troubleshoot since the mod is closed-source, so most of it ends up being guess-work. Though at least it seems to have resolved upon a reinstall, which is good. Sorry I couldn't assist further.

Have you tried an instance using only FD, JEI and Optifine?

Hi there, @Whiskey-Sunshine! Just checking in for an update. Did the issue resolve? If not, did you test the suggestion above?

I'll close it for now, since it has become stale. If the problem persists, feel free to reopen this issue and run the steps above. 👍
