Yes gui works with a 2d canvas to draw shape and texts, so scaling means scaling the source canvas and the corresponding webgl texture as this is not shared memory.
I figure that scaling would tell Babylon to raster the image at the scaled down resolution, then pass it over to the GL. That’s why I’m not quite following the high GL memory usage here.
I am not sure what you mean by scaled down here as you put a parameter to actually increase its size by ten times what it would normally be
