Echo flickering when drawing to the programmable block's surface

Blargmode shared this bug ago

Outdated

Effect can be seen here:

This code can reproduce it (it's what's running in the gif):

IMyTextSurface surface;

float[] heartBeat = {1, 1.3f, 1.5f, 1.3f, 1, 1.3f, 1.5f, 1.3f, 1, 1, 1};
int heartBeatIndex = 0;

public Program()
{
	surface = Me.GetSurface(0);
	surface.ContentType = ContentType.SCRIPT;
	surface.Script = "";

	Runtime.UpdateFrequency = UpdateFrequency.Update1 | UpdateFrequency.Update10;
}

public void Main(string argument, UpdateType updateType)
{
	if ((updateType & UpdateType.Update10) != 0)
	{
		heartBeatIndex++;
		Echo("Text");
		
		using (var frame = surface.DrawFrame())
		{
			MySprite sprite = new MySprite(SpriteType.TEXTURE, "SquareSimple", color: Color.White);
			sprite.Size = Vector2.One * 50 * heartBeat[heartBeatIndex % heartBeat.Length];
			frame.Add(sprite);
		}
	}
}

If Update1 is removed, the flickering stops. But as you can see, no drawing or Echoing is happening during Update1, so that shouldn't matter.

Also, it only flickers when the content of the surface changes.

I have the same bug
