Some of my blocks need little laser beams and because they need to be kind of flimsy and flickery, I am rendering them with a TESR. When the TESR renders the console gets spammed with this error:

########## GL ERROR ##########
@ Post render
1280: Invalid enum

I read somewhere that this can be caused by specific graphics card models but I doubt this is the cause as I am using a GTX 1080.

 

This is my TESR:

package XFactHD.rssmc.client.renderer.tesr;

import XFactHD.rssmc.common.blocks.gadget.TileEntityKapkanTrap;
import net.minecraft.client.renderer.GlStateManager;
import net.minecraft.client.renderer.Tessellator;
import net.minecraft.client.renderer.VertexBuffer;
import net.minecraft.client.renderer.tileentity.TileEntityRendererDispatcher;
import net.minecraft.client.renderer.tileentity.TileEntitySpecialRenderer;
import net.minecraft.client.renderer.vertex.DefaultVertexFormats;
import net.minecraft.util.math.Vec3d;
import org.lwjgl.opengl.GL11;

public class TESRKapkanTrap extends TileEntitySpecialRenderer<TileEntityKapkanTrap>
{
    @Override
    public void renderTileEntityAt(TileEntityKapkanTrap te, double x, double y, double z, float partialTicks, int destroyStage)
    {
        Vec3d laser = te.getLaser();
        GlStateManager.pushMatrix();

        Tessellator tess = Tessellator.getInstance();
        VertexBuffer buffer = tess.getBuffer();

        //GlStateManager.disableLighting();
        //GlStateManager.enableBlend();
        //GlStateManager.tryBlendFuncSeparate(770, 771, 1, 0);
        //GlStateManager.disableTexture2D();

        buffer.setTranslation(x, y, z);
        GlStateManager.glLineWidth(2F);
        buffer.begin(GL11.GL_LINE, DefaultVertexFormats.POSITION_COLOR);
        buffer.pos(0, 0, 0).color(1, 0, 0, 0).endVertex();
        buffer.pos(laser.xCoord, laser.yCoord, laser.zCoord).color(1, 0, 0, 0).endVertex();
        tess.draw();
        buffer.setTranslation(0, 0, 0);

        //GlStateManager.enableTexture2D();
        //GlStateManager.disableBlend();
        //GlStateManager.enableLighting();

        GlStateManager.popMatrix();
    }
}

No matter if the currently commented lines are commented out or not, the error persists.

 

PS: For the No-TESR advocates: I will be making this into a FastTESR when it works if it is doable.

Oh, ok. I'll try that.

That fixed the error but the line still doesn't render (or at least I can't find it). I tried cranking up the line width to 10 but that didn't get me anywhere.
