Can confirm
Comment 2 ratijas 2023-06-20 12:58:38 UTC 
Flatpak's icon resolution algorithm is quite different from what we normally use, so there's a specific function in flatpak-kcm code which performs a best-effort search, and as seen in this bug report it is far from ideal.

There is a one open MR to provide at least sensible fallback icon, but it got stuck on the lack of an appropriate icon. See https://invent.kde.org/plasma/flatpak-kcm/-/merge_requests/61

Comment 7 Patrick Silva 2025-09-21 13:56:43 UTC 
There is an icon for OBS Studio, but it is wrong. Correct icon is a circle, the icon in the KCM is a square.
Comment 8 Justin Zobel 2025-09-22 00:44:05 UTC 
Is it the square as shown in the screenshot in the first comment?
Comment 9 Patrick Silva 2025-09-22 00:46:46 UTC 
No. It's OBS icon, but in square form.
Comment 10 Nate Graham 2025-09-23 15:13:10 UTC 
I can't reproduce that. OBS and Swell Foop's icons looks correct in the KCM for me with today's git master.

Both apps are installed from Flathub. Same for you?
Comment 11 Patrick Silva 2025-09-23 15:27:49 UTC 
Yes, both are installed from flathub. Fortunately I'm unable to reproduce today.
