DotStim motion displacement is not computer properly

Hello there. I am using PsychoPy 1.82.01 to present several RDKs.

There is a bug report (#781) on GitHub about incorrect displacement of dots in DotStim class: the new position per frame seems to be scaled by the field size so that, e.g., for motion speed of 1 dva/s the actual presented speed is fieldSize*1 dva/s.

I can confirm this bug. So, I am wondering has this been resolved in the newer PsychoPy versions? If not, are there any plans to do so? This bug affects the RDK presentation dramatically.

Cheers, Dragan

I think this is now fixed in
