Is there a way to fix low quality app images in Software Center? Its so essential thing for software center become really useful. Yes I can always look from flathub than install from terminal but that entirely defeats the purpose of having a graphical Software Center in the first place, making the user experience feel incomplete and frustrating.
Also, on Flathub, we can view images full screen, unlike in the Software Center. I'll pass on that for now. At least, is there a command to set the resolution of the images or change their location to Flathub itself?
Hmm ... the Pictures are good for me. How are Your Hardware Specs? And run Your System in Wayland or X11? You can check this in Settings>About.
Did you tried to end the Process and start it again. So it loads again. To do that, open the Software Center and let it open. Then open the System Monitor and look for the Process gnome-software and end the Process. You will see that the Software Center Window will disappear; that is intended. Then open the Software Center again and look if the Pictures are better now.
I normally use wayland but I also try x11 result was same. Also resetting reinstalling gnome-software not work.
I use 15 inch laptop by the way. I'm surprised you said the pictures were good. I thought everyone had the same problem. Maybe problem caused from monitor size somehow. What kind of monitor do you use?
I suspect the monitor size calculation is poorly done in app. I encountered a similar issue when developing WinForm applications. It seemed fine when running on a 15-inch laptop, but running the same application on a larger screen caused size and quality issues. Perhaps a similar issue exists in Gnome Software too.
Comparing the two images, the Gnome Software screenshot looks a bit blurrier to me.
Your thinking is sound, but the culprit is how Gnome Software gets the metadata.
So, it is an issue within the app.
Gnome Software does not fetch metadata directly from Flathub.org. It uses AppStream metadata provided by Flatpak remotes which are XML files and associated assets (like screenshots) hosted separately.
The Gnome Software store likely is caching smaller preview images to reduce memory and bandwidth usage as well as the Flatpak metadata might include lower-resolution images for performance reasons.
Gnome Software doesn’t offer full-resolution image viewing. It displays screenshots at a fixed maximum size in the GUI, even when higher-res images are available.
I admit, I can see a good reason for this. Gnome Software trades off fidelity for performance by preloading lighter assets.
There are no terminal commands or settings that can be adjusted on this since this is hard coded into the Gnome Software store.
A workaround might be to install Bazaar to manage your Flatpak packages - I am not sure if it manages metadata differently.
My Hardware isn't the most powerful, too. I have an AMD Ryzen 3200G (slighty overclocked 4Ghz CPU, 1600Mhz iGPU). My Monitor is my TV-Screen (50 inch Sony).
I see on your Neofetch Picture that You have Nvidia Graphics. On Zorin 17, I would recommend to use X11 for Nvidia Graphics Usage because it works better together. What Nvidia Driver do You use?
Also I see, you have an internal Intel Graphics. Is this active or do You use only the Nvidia Graphics?
Oh, and another Thing: Do You have any third-party Gnome Extensions active?
I understand there aren't any perfect solutions for Gnome Software at the moment. As Aravisian mentioned, it seems to use smaller preview images. Additionally, my screen's width-to-height ratio is a bit different from the Ponce-De-Leon preview image, which might also contribute to the issue. Even so, Ponce-De-Leon's screenshot still isn't as crystal clear as the Flathub website.
I will check Aravisian answer as solution. I will probably use new app store advice Bazaar or creating a Flathub Electron app for searching, and then downloading from the terminal. It's not an ideal solution, but given the circumstances, there isn't much else that can be done.
