It seems that whenever the game shows the text of an hoverEvent (caused by /tellraw, hovering over an item in the inventory...) it changes the lighting of entities.
- Displayed block of minecarts (darkens)
- Ender crystal (brightens)
- Place a minecart displaying a block:
- Stand in front of it (South direction; +Z) and look at it (looking North; -Z)
- Use the following command and hover over the text:
→ You should see that the block being displayed darkens when you are hovering over the message.
The following is based on a decompiled version of Minecraft 1.9 using MCP 9.24 beta.
It looks like the method net.minecraft.client.gui.GuiScreen.drawHoveringText(List<String>, int, int) which calls the method net.minecraft.client.renderer.GlStateManager.enableRescaleNormal() is causing this.
