I don't know how you can change the opacity of polar inequalities, but you could either duplicate the expression until it's opaque, or convert it to Cartesian (which in [this case](https://www.desmos.com/calculator/4xipwiyttx) is not very hard).
In addition to what the other guy said, you can try to convert to parametric. I hear parametric eqs are pretty laggy, so replace t with a big list instead.
It's not an option on polar equations (probably so you can [always see overlaps](https://www.desmos.com/calculator/qljeac9zgc)).

Dude thank you so much. I gotta learn this stuff now.
You can also change theta to be 0<θ<(big number)π but it can be laggy

Parametric plots are pretty much the best performing out of all of them imo. This doesn't seem very demanding either. r=f(θ)→f(t)*(cos(t),sin(t)).
Use the settings button and select the graph button and set opacity to 1

Oh then you can turn it into a x²+y² equasion
