URL of experiment: project [PsychoPy] (the issue arises at the 3 slide, where the screenshot of a webpage is displayed, nevermind the errors after that)

PsychoJS 2023.1.0, PsychoPy 2023.1.0, tested on multiple browsers (Safari, Opera, Chrome, Yandex Browser)
Hello! I’m trying to set up an online experiment. The problem is, the images are getting “blurred” when run online - compared to what I see on my screen locally. The screenshot attached is how it looks like when I run it using PsychoPy locally, the screen recording is how it looks online using Pavlovia.
On the screen recording there is also a process of zooming in/out during the experiment - on 50% scale it looks exactly like I see it locally. I therefore assume that it is something that is related to downscaling of the images (i.e. it is full-scale locally, but when uploaded online it’s downscaled to match online resolution).
The questions are:
- Is there any way I can make the images seem in high-quality on any device?
- I use the same laptop for testing online and offline, I’ve tried both with and without the
fullscrparameter set to be True. However in the browser the resolution is lower than the one I get in the desktop app - can I make it match the monitor resolution rather than the browser?
p.s. the image i’ve uploaded got downscaled to 1920x1200, its original size is 3584x2240. same for scaling in the video, but you could still see the issue when upscaled to 200% or you could test it manually in your browser
