Debug chunk boundary rendering does not work
belak opened this issue · 10 comments
Expected Behavior
When chunk boundary rendering is on, boundaries between chunks should be rendered.
Actual Behavior
There are no rendered chunk boundaries
Reproduction Steps
- Press F3+G to enable chunk boundaries
- See that chunk boundaries are not rendered
System Information
- OS: macOS 10.14.6
- Java Version: 1.8.0_74 64bit
- CPU: i7-7820HQ
- GPU: Radeon Pro 660
- Fabric Loader 0.9.0+build.204-1.16.1
As far as I can tell, it's stuck at Oneshot (GL 2.0) for some reason even though macOS should support 3.0. Also, I don't see "Video Settings > Performance", though I do see the renderer in "Video Settings > Advanced".
This was originally seen on a server but it also happens in a fresh world as well.
I cannot reproduce this issue. There might be some kind of specific weirdness with the OpenGL driver in macOS.

Minecraft still uses parts of the fixed-function pipeline in rendering, which means that in order to use modern OpenGL features, it needs to use a compatibility profile. macOS does not support these compatibility profiles, and generally it also doesn't support any extensions which would otherwise allow us to use these newer features in older versions of OpenGL.
So, at best, you're stuck with OpenGL 2.1 when playing Minecraft on a Mac computer. We can't do anything about this until Mojang makes the necessary changes in their game, unfortunately.
So, when using ./gradlew runClient the chunk boundaries display, but when copying the mod into the mods folder of the current MC profile, it doesn't display.
Is there anything else I could do to help debug this?
Hi @belak, I've spent a few days trying to reproduce this. When that failed, I tried looking for someone with access to your hardware configuration. FemoralArtistry suggested in JellySquid's discord that you may have reducedDebugInfo enabled in your personal instance. This would hide the chunk borders (something I was not aware of). This would explain why it works in a dev environment, but not in your personal instance.
Can you try disabling it, and let us know if that fixes the issue? To do so, set /gamerule reducedDebugInfo false (if applicable), then check Options > Chat Settings > Reduced Debug Info.
Bumping this thread to say that the solution above worked for me. I am using Multidraw (GL 4.3) on Windows 10, and chunk borders did not appear until I changed Options > Chat Settings > Reduced Debug Info to OFF.
