[1.19] Custom head rendering problem

[grossik]

Hi.
I'm having trouble rendering my own head. If I place a head that has my skin texture and another one next to it (without texture - completely black) my skin is visible on the second one until the first head disappears from view. 
How to make the second head always be all black?

Code:

public class CustomSkullRenderer implements BlockEntityRenderer<CustomSkullBlockEntity> {
	
	SkullModelBase headModel;
	RenderType rendertype;
	DynamicTexture texture;
		
	private int[][] oldTextureMap;
	
	public CustomSkullRenderer(BlockEntityRendererProvider.Context context) {
		headModel = new SkullModel(context.bakeLayer(ClientSetup.HEAD));
		rendertype = null;		
		oldTextureMap = new int[16][32];
		
		texture = new DynamicTexture(64, 64, true);
	}
	
	@Override
	public void render(CustomSkullBlockEntity be, float p_112308_, PoseStack pose, MultiBufferSource buffer, int light, int p_112312_) {  
		try {
			updateImage(be);
			if(rendertype == null) {
				Minecraft.getInstance().getTextureManager().register(be.getLocation(), texture);
				rendertype = CustomRenderType.createSkullRenderType(be.getLocation());
			}
		} catch(Exception e) {
			e.printStackTrace();
		}
				
      BlockState blockstate = be.getBlockState();
      boolean flag = blockstate.getBlock() instanceof CustomSkullWall;
      Direction direction = flag ? blockstate.getValue(CustomSkullWall.FACING) : null;
      float f1 = 22.5F * (float)(flag ? (2 + direction.get2DDataValue()) * 4 : blockstate.getValue(CustomSkull.ROTATION));
      
      pose.pushPose();
      if(direction == null) {
      	pose.translate(0.5D, 0.0D, 0.5D);

      }

      pose.scale(-1.0F, -1.0F, 1.0F);
      VertexConsumer vertexconsumer = buffer.getBuffer(rendertype);
