Disappearing water with VBOs + Render Regions on AMD

[omega9380]

I've been getting a strange issue when playing with VBOs enabled. I'm running pre3, but I have had this glitch since alpha8.

When VBOs are enabled, and I'm running Optifine, water will disappear, apparently based on the direction I'm facing. I've tried several worlds, I've tried enabling and disabling shaders, I've tried several different resource packs as well as no resource pack. It occurs whether I'm playing single player or on a server.

Here are screenshots of the issue:

Here is the log file from the session I took the screenshots in:

latest.log

And here is a debug crash log:

I would really love to play with VBOs, I get at least 10fps better with them enabled, if not more. Thanks!!

[omega9380]

Anyone? Any ideas at all?

[HanPrower]

Someone else posting on the BDcraft forums with the same issue with Radeon RX 580 and disabling VBOs fixing it.

Sadly no extra technical information, just a +1: https://bdcraft.net/community/help-centre-f4/water-for-farm-bug-purebdcraft-128x-mc114zip-t7182.html

[sp614x]

This seems to be specific to AMD, probably only Radeon RX 580 and may also depend on the driver version.

[sp614x]

Looks like it is caused by Render Regions + VBOs:

[Truhard]

This issue persists on the latest Optifine version, 1.16.5 G8 pre9. It's not specific to the RX 580 or a driver version. (Shown on G7 due to #5458)

Debug log:

crash-2021-03-22_19.55.51-client.txt

@sp614x Not sure if you still know about this issue. If necessary I can try to recreate it on an Optifine only client, however I don't believe it is related to forge, mods, or shaders (could be wrong).

[Truhard]

It seems that the angle the region is viewed at changes whether blocks disappear or not.

[sp614x]

Can you reproduce it with only Forge and OptiFine (no other mods)?

[Truhard]

No, but I found exactly what causes it.
If a Mekanism wind generator is placed above y80 without a block touching its face with render regions on, it causes the issue.

I'm assuming this only occurs when the wind generator model is loaded(?) since the issue goes away when the model isn't in view (shown in video below)
