Description Abdul Aziz 2025-09-03 07:30:06 UTC

When switching between **Breeze Light** and **Breeze Dark** in **Quick Settings**, Plasma also resets the icon theme back to Breeze.

I think this behavior is unnecessary. A light/dark toggle should only change the **color scheme**, not override the **user’s chosen icon theme**.

---

# Steps to Reproduce

1. Set a non-Breeze icon theme (e.g., Papirus, Tela, etc.).
2. Open Quick Settings.
3. Toggle between Breeze Light and Breeze Dark.

---

# Actual Result

The icon theme resets to Breeze.

---

# Expected Result

Only the **color scheme** should change. The **icon theme** should remain as set by the user.

Quick Settings switches global themes, not color schemes, and that's intentional at this point in time.

There's actually a good reason for it: only switching the color scheme will result in unreadable icons in GTK apps, because the icons in the Breeze Light icon (or any icon theme, really) theme can't be recolored by GTK apps due to mutually incompatible implementations of icon recoloring.

If and when that gets resolved — ideally due to some cross-desktop collaboration regarding icon recoloring — we'll be able to change the implementation to only switch the color scheme.

Until and unless that happens, we have to keep this the way it is to prevent foot-guns for users who aren't familiar with the underlying implementation of all this theming stuff.
