Screenshot link since I can't just upload an image for some reason.

I got the PixelOver demo so I could try it out before buying it in the future, but whenever I open it up the UI is scaled up by a lot for some reason. It makes it pretty much unusable and I was sent here to report any errors. I'm using the app on Steam Deck in Desktop mode.

It's really surprising. The zoom is normally calculated with the size of the screen.

Impossible to reach the settings with the UI from your screenshot. But what you can do is to go on app settings file (~/.local/share/PixelOver/settings.cfg) and add this following text :

[interface]

scale_select=1

scale=100.0

If it doesn't work that mean the interface wasn't scaled (the unity is % so 100 is unscaled) so you will need to put a value below 100 (like 25 for example)

Yes i checked with someone the DPI is false for the steam deck that's why the scale is badly computed. I'll need to check that

Now fixed in 0.13, added a security to prevent this behavior.
