Description Chris Harris 2025-10-07 08:32:44 UTC 
SUMMARY
Installing a PWA using Google Chrome saves all the icons in the manifest under folders labelling their resolution. However, the Plasma task switcher using the large icons setting shows a low resolution version of the icon. I tried deleting all the icons except the 512px one, and it still shows a low resolution one even after a reboot.

STEPS TO REPRODUCE
1. Install a PWA (e.g. my own site, https://www.kleardecision.com) using Google Chrome
2. Open the installed app
3. Toggle the switch window modal with large icons

OBSERVED RESULT
The PWA's icon shows in low resolution

EXPECTED RESULT
Show's the icon in the correct resolution

This seems to be a Chrome issue. It sets a desktop file but also sets a custom window pixmap on the window and for apps it only sets a 32px pixmap. This should be reported to Chrome.

Interesting, that's why I couldn't find the 32px version anywhere. Thanks Kai, I'll take it up with Chrome.
