OpenGL error spam ('GL_INVALID_OPERATION error generated. Depth formats do not match.') in logs with Immersive Engineering + Estrogen when shaders enabled

[lulunexi]

What happened?

I was testing a pack with Oculus, Immersive Engineering, and Estrogen among others. After enabling shaders, I noticed my logs were being spammed every ~10-20ms with

[Render thread/INFO] [mojang/GlDebug]: OpenGL debug message: id=1282, source=API, type=ERROR, severity=HIGH, message='GL_INVALID_OPERATION error generated. Depth formats do not match.'

I eventually narrowed the spam down to just these 3 mods, the error only occurs with all 3 and shaders enabled. The spam doesn't occur if only 2 of the mods are installed, or if shaders are just disabled.

Minimal Reproduction List

• Oculus 1.8.0
• Estrogen 5.0.8+1.20.1
• Immersive Engineering 1.20.1-10.2.0-183

Reproduction Steps

1. Install 1.20.1 Forge 47.4.10
2. Install Oculus + Embeddium
3. Add Immersive Engineering + Estrogen
4. Load a world
5. Enable a shaderpack
   Spam continues until shaders are disabled.

Related Issue(s)

The closest related reports seemed to be Issue 71, and Issue 47. They both had the exact same
'GL_INVALID_OPERATION error generated. Depth formats do not match.'
spam, but those reports only required Immersive Engineering and the issue appears to be resolved.

This issue only occurs when both Immersive Engineering and Estrogen are installed with Oculus and shaders enabled, which makes this a different issue.

If we follow what DejaVuMan said (according to others) in issue 71, it's possible that this could be ignored entirely (shaders are also working fine on my end, with no noticeable FPS drop) but I figured it was worth the report at least.

Some people say that these are "false flag" errors and aren't actually an issue - shaders seem to be working fine, but can't be sure (also to clarify, this is on an Nvidia GPU)

There were some other old issues I saw with IE and a similar 1282 error but they had a different end bit, ex. Issue 513 that has <texture> is not a valid texture name. instead of Depth formats do not match, so I don't believe those ones are related.
