Problem with slider component when exp runs in local browser

Description of the problem:

Dear all,

I’ve started to create my experiment in PsychoPy builder with the intention of running it online. What I have created so far runs perfectly well via Python, but the online equivalent of it in JS does not.

Here I will ask exclusively about my slider component, which is probably a simple issue but I do not really know about JS. For whatever reason, it does not show as it should. You can see the difference in the screenshots below:



You can see that in the JS case the slider is just a light gray rectangle. The ticks and their labels disappear and the selection (in red) takes half of the rectangle. Also, you can see two gray slider labels “floating” around the output “not enough”.

I do not know how to fix that. This happens regardless of whether I run the experiment in Firefox or Chrome.

I am using PsychoPy v2013.1.2. My .psyexp file is attached in case you want to check it out!

Thank you very much in advance!
