Wrong Tray-Icon on KDE (Fedora)

[mibeon]

Description

Guys, it's almost 2026 and we can't change the white icon of docker desktop in our KDE taskbar. 🥳

Why do this app not even support automatically change depending on light/dark taskbar?

Do anyone know any hack, break or workaround for this shit?

My specs:

• Fedora 43
• Plasma 6.5.4
• Kernel 6.17

Thanks for any help!

Reproduce

1. Install docker and docker desktop as described in official docs on a linux with KDE DE
2. Start docker desktop having light mode on (taskbar and apps)
3. See how "beautiful" this white icon is

Expected behavior

I a miracle world this app would check which theme is on and provide the related icon.

We need one more icon, guys. Not one, we need two.

• Light icon, if the taskbar or the full system is using dark mode
• Dark icon, if the taskbar or the full system is using light mode

And if there is no chance for do it on the fly, there is always an option, to let us do it manually. Yes, we would do it also manually. Can you imagine it?
