I thought of rendering the stuff into a metasurface, and then, knowing the size of the result, transform it and embed into the target image, which is a png, usually. However, when doing so I notice the text looks a bit worse (see example attached). Is it supposed to go like this?

I suggest that you always create a temp surface of the same type as your final
target.  Font settings defaults differ from surface type to surface type...
You can create a 0x0 temp surface.  Works just as well.
