Jagged circles in online experiment

[bets]

Description of the problem: I am using psychopy v2020.2.0. Even though I increase the num of vertices, the circles in my online experiment look jagged. How can I fix? Thanks in advance.

This topic has been created before, but I couldn’t find a working solution since I created the experiment in the builder.
I am using pixel as unit.

Would it be appropriate to increase the thickness of the border? 1 pixel is bound to give a jagged edge.

Thanks a lot for your help. Even if I change the line thickness to 2, it looks jagged. What do you think I should change?
By the way, it looks smooth in psychopy, this problem only exists in pavlovia.
Here are the properties:

Also, I upgraded psychopy to 2020.2.10. However, the circles are still jagged in pavlovia.

You could try the latest version. However anti-aliasing is not as good online as locally.

Visual stimulus edges appear blurred

Hi @toto, do you mean that the circle edges are pixelated ie. there is no antialiasing? If so you may be interested in the issue I created today on psychopy’s github page: I’ve managed to solve that issue by creating the window object with different parameters (see the issue above, the solution was suggested here) - this can not be done in the Builder directly unfortunatelly (AFAIK). But you could add a code component that replaces automatic builder window with a custom one. Let me know if yo…

Best wishes,
