hdr = true seems to disable antialiasing.
I believe this is a bug since the documentation for the
hdr flag to
The HDR value should be
trueas long as possible, unless you’re targetting cheap fallback for low end devices. This value allow one of the half float or float texture type, depending on the GPU. Also, some effects (like bloom) will be more accurate.
This very much suggest that you should try and always keep HDR on for the best image quality.

Here is a screenshot of it with
hdr turned on (default) and off (modified pg):
I have also made my own more basic playground. Here is the results with
hdr = true:
Here is the exact same playground with
hdr = false:
Notice the drastic differance. This seem to affect both edges against the background (same result with transparent
clearColor btw), the edges against the plane and also the intersection edge between the spheres which end up kinda funky.
