Description of the problem: When I run my Study offline everything looks good.

But if I try to run the Study online this happens:

This is how I created the sliders:

Yes, the issue is that getting alignment right across devices and different rendering methods is just hard! But the scales do look badly labelled here.

Will see what’s going wrong

Did you find anything out?

I think it’s very weird tbh that the scales are this different. I don’t know how I could possibly figure out a way to have it look ok on all devices if there is this big of a discrepancy.

It’s also weird because it works for the Text and Picture but only the scales are a mess.

I think I am experiencing a quite similar problem - when I run my Study offline everything looks good


But if I try to run the Study via Pavlovia everything is rescaled.

Windows size [1280, 720] is not editable in Bilder -> Experiment Setting -> Screen,
so I do not have an idea how to solve the issue.

Any idea how to solve it?

Hi @Lukamark what screen units are you using for your experiment?

@dvbridges
Do you mean how I position the elements on the screen? By X,Y coordinates between [-1,1] through [0,0] to [1,-1]

No, I was just checking what screen units you have been using

I do not think it is relevant, but it could actually be a source of difference if you are using units that are not supported online e.g., visual degree units are converted to height units. I think this related to something else that Jon was looking in to.
