[1.12.2] Custom GuiButton Drawing Artifacts

[KittenKoder]

I have this button I extended from GuiButton because I couldn't get the regular texture button to work. Here's the class:

 

package com.kittenkoder.magitech.gui;

import net.minecraft.client.Minecraft;
import net.minecraft.client.gui.GuiButton;
import net.minecraft.client.renderer.GlStateManager;
import net.minecraft.util.ResourceLocation;
import net.minecraftforge.fml.relauncher.Side;
import net.minecraftforge.fml.relauncher.SideOnly;

@SideOnly(Side.CLIENT)
public class MagitechGUIButtonTexture extends GuiButton {
	protected ResourceLocation _texture;
	protected int _texx, _texy;
	
	public MagitechGUIButtonTexture(int buttonId, int x, int y, int widthIn,
			int heightIn, ResourceLocation texture, int tx, int ty) {
		super(buttonId, x, y, widthIn, heightIn, "");
		this._texture = texture;
		this._texx = tx;
		this._texy = ty;
	}
	
	public void setTexCoords(int x, int y) {
		this._texx = x;
		this._texy = y;
	}
	
	public void drawButton(Minecraft mc, int mouseX, int mouseY, float partialTicks) {
		if(!this.visible) return;
        mc.getTextureManager().bindTexture(this._texture);
        GlStateManager.color(1.0F, 1.0F, 1.0F, 1.0F);
        GlStateManager.enableBlend();
        GlStateManager.tryBlendFuncSeparate(GlStateManager.SourceFactor.SRC_ALPHA, GlStateManager.DestFactor.ONE_MINUS_SRC_ALPHA, GlStateManager.SourceFactor.ONE, GlStateManager.DestFactor.ZERO);
        GlStateManager.blendFunc(GlStateManager.SourceFactor.SRC_ALPHA, GlStateManager.DestFactor.ONE_MINUS_SRC_ALPHA);
        this.drawTexturedModalRect(this.x, this.y, this._texx, this._texy, this.width, this.height);

	}

}

 

The problem is that it's drawing something odd to the right of the GUI, here's an image:

 

It looks like it's drawing one of the texture coordinates there as when I change the buttons' contents (which only changes where it gets the texture piece from) the artifacts change. Did I forget to override something? The Gui and GuiButton source hasn't offered much clues into this. In case it's the GUI that the buttons are being added to, here's that:

On this, in insight would be helpful to get rid of it.
