Antialiasing change Point sprite size [2021.11180 WIN10]

Bugs

Hi,
It appears that anti-aliasing in renderTOP affects the size of point sprite quad when set higher than 16x(Medium).
I made a little .tox example to demonstrate the issue, for me the size of the point sprite is correct when anti-aliasing is set at “16x(Medium)” or lower, if I choose “16x(High)” or “32x”, the point sprite quad is reduced to half its size.
The example includes a renderpicker, you can see that when the point sprite quad is reduced, the renderpicker still detects a quad of the correct size.
Hope this helps,
Colin.

Interesting behavior. This is built into the GPU though, not something we can control. It must be deciding the point sprite size based on the size of the sampling grid, which gets finer at higher values. Not sure why it doesn’t get smaller at 8x vs 4x though
