Expected Behavior

Normally water doesn't clip through water-logged blocks like stairs.
See this screenshot (vanilla):

Actual Behavior

Sodium-fabric causes these water-logged oak stairs to have water clip through them.

Reproduction Steps

Build what was done in the screenshots.

System Information

• Java Version: 1.8.0_51 64bit
• CPU: Intel(R) Core(TM) i7-4790K
• GPU: GeForce GTX 1080

Enabled in the mod:

• Chunk Renderer: OpenGL 4.6

Does this issue disappear if you use the OpenGL 3.0 renderer or disable the Compact Vertex Format option in Video Settings > Performance?

Turning "Use Compact Vertex Format" off fixes this issue. Tried and tested for OpenGL 3.0 & 4.6

@StealWonders Does this issue still occur after the recent changes to Sodium? I'm not able to reproduce this problem, but there have been other user reports.

This issue is fixed with the latest build. Closing issue :-)
