Different icons in taks switcher and panel

SUMMARY
After installing both Chromium (deb) and Ungoogled Chromium (flatpak), Plasma variously displays mismatched icons.

STEPS TO REPRODUCE
1. Install and run Chromium (I use ppa:savoury1/chromium repository).
2. Check the icons shown everywhere in Plasma. They should be default blueish Chromium logos.
3. Install and run Ungoogled Chromium https://flathub.org/cs/apps/io.github.ungoogled_software.ungoogled_chromium
2. Check the icons of both apps. Whereas Ungoogled Chromium should have redish icons as shown on Flathub page, original Chromium should keep its blueish logos.

OBSERVED RESULT
Blue and red Chromium icons are mixed in a different way:
1. Icons in app launcher (alt+f1) are correct.
2. Icons in app switcher (alt+tab) are correct as well.
3. Window icons (left upper windows corner) are correct.
3. Icons on "Icons-and-Text Task Manager" panel are only red.
4. Icons in notifications popped from the panel are only red. Moreover the notifications says "Ungoogled Chromium" even if the action was fired from Chromium (original).

EXPECTED RESULT
All icons everywhere in the Plasma UI is shown in respect to the application of origin.

SOFTWARE/OS VERSIONS

ADDITIONAL INFORMATION
I never noticed such behavior until Plasma 6. Discovered in Plasma 6.0 till now. However Ungoogled Chromium used to have blueish icons those days: https://github.com/ungoogled-software/ungoogled-chromium-flatpak/issues/3
I use KDE Neon with Breeze Twilight theme and Oxygen iconset.
I use "Big icons" task switcher and Icons-and-Text Task Manager panel.

This is a quirk/bug (depending on how you want to define it) of the way KWin's task switcher works. It doesn't use the same icon heuristics as the Task Manager, which can cause mismatches between the two sometimes.

Comment 3 Michal Kec (MiK) 2024-08-04 10:37:16 UTC

Hello Nate, thank you for considering this bugreport. However I'm not sure this issue is actually a duplicate.

1) bug 459735 is two years old. It is reported for Plasma version 5.25.5, but I noticed this behavior after upgrading to Plasma 6.

2) In bug 459735 comment 1 you stated "Task Manager icon uses the icon from the app's .desktop file". I've double checked my apps and both provide the correct icons in their respective .desktop files:

[mik@desktop applications]$ grep Icon chromium-browser.desktop
Icon=chromium-browser

[mik@desktop applications]$ grep Icon io.github.ungoogled_software.ungoogled_chromium.desktop
Icon=io.github.ungoogled_software.ungoogled_chromium

I believe this issue is not related to different heuristics for task switcher and Task Manager, it is a faulty heuristic in Task Manager. Otherwise I could fix it by editing the .desktop files right? Could you please reconsider your conclusion?

Comment 4 Nate Graham 2024-08-06 18:48:23 UTC

Ok, you're right, my mistake. I was skimming based on the title.

I can't reproduce the issue on Wayland. Dies it only happen to yo on X11, or on Wayland too?

Comment 5 Michal Kec (MiK) 2024-08-08 13:50:18 UTC

Hello Nate, thank you for your reconsideration!

Yes, I can reproduce the issue on both X11 and Wayland.

Two different icons during startup of one app

Two more observations, I've just noticed:

1. I had (original) Chromium open before logging out. I am using app session recovery. However, the next time I logged in, Ungoogled Chromium was restored.

2. When you start the (original) Chromium browser, you will see two different icons for a while. See attached video. Same for X11 & Wayland.

Comment 7 Michal Kec (MiK) 2024-12-21 10:40:34 UTC

I can confirm this bug has been fixed by upgrading to KDE Neon 6.2 (based on Ubuntu 24.04) and Plasma 6.2.2. All icons are correct in both X11 and Wayland. Thank you!
