### Bug description
As the undermentioned screenshot demonstrates, the ~~toolbar~~ [^1] button iconography is absent:
1. #### The Homepage
`org.kde.breezedark.desktop` | `org.kde.breeze.desktop`
-|-
 | 
1. #### The Distribution Configuration Flyout
`org.kde.breezedark.desktop` | `org.kde.breeze.desktop`
-|-
 | 
1. #### The Account Action Context Menu
`org.kde.breezedark.desktop` | `org.kde.breeze.desktop`
-|-
 | 
However, this doesn't affect the configuration window:
This is a *partial* recurrence of [`issues/6594#issue-2213769118`](https://github.com/nextcloud/desktop/issues/6594#issue-2213769118) - a regression.
### Steps to reproduce
1. Install [`nextcloud-client-3.14.2-1.fc42`](https://fedora.pkgs.org/rawhide/fedora-x86_64/nextcloud-client-3.14.2-1.fc42.x86_64.rpm.html) (as a dependency of [`nextcloud-client-dolphin-3.14.2-1`](https://fedora.pkgs.org/rawhide/fedora-x86_64/nextcloud-client-dolphin-3.14.2-1.fc42.x86_64.rpm.html)):
```sh
#!/usr/bin/env sh
sudo dnf install 'nextcloud-client-3.14.2-2.fc40.x86_64'
```
3. Invoke the GUI:
```sh
#!/usr/bin/env sh
nextcloud-client
```
### Expected behavior
The icons should be rendered.
### Which files are affected by this bug
[`/usr/bin/nextcloud`](file:///usr/bin/nextcloud) (per `command -v nextcloud`)
### Operating system
Linux
### Which version of the operating system you are running.
[`Fedora-KDE-Live-x86_64-40-1.14.iso`](https://download.fedoraproject.org/pub/fedora/linux/releases/40/Spins/x86_64/iso/Fedora-KDE-Live-x86_64-40-1.14.iso)
### Package
`packages.fedoraproject.org/pkgs/nextcloud-client/nextcloud-client`, via `dnf5`
### Nextcloud Server version
[28.0.10.1](https://wim.nl.tab.digital/status.php#:~:text=version%09%2228.0.10.1%22)
### Nextcloud Desktop Client version
1. [`3.14.2-1.fc42`](https://fedora.pkgs.org/rawhide/fedora-x86_64/nextcloud-client-3.14.2-1.fc42.x86_64.rpm.html#:~:text=Package%20version%20%093.14.2,Package%20architecture%20%09x86_64)
1. `3.16.3-2.fc42`
### Is this bug present after an update or on a fresh install?
I don't know, but I presume that it updated from a minor version (ex. 3.4.2 to 3.4.4).
### Are you using the Nextcloud Server Encryption module?
I don't know.
### Are you using an external user-backend?
I don't know.

I can confirm this behaviour. As soon as I start Nextcloud like this, the Problem diappears: QT_QPA_PLATFORMTHEME=gtk3 ./nextcloud
Seems QT-related somehow.

@BatmansGehilfe , if I don’t receive an answer here eventually, I’ll file an issue at KDE BZ. That’ll at least ensure it’s either triaged as KDE’s or upstream Qt’s fault.

From what I’ve noticed, upstream Qt’s qqc2 styles are not at fault. KDE’s qqc2 style is at fault. You should file an issue in bugzilla or invent against qqc2-desktop-style. What happens when you use QT_QUICK_CONTROLS_STYLE=org.kde.breeze environment variable with nextcloud client?

@hazelbunny , I’ve filed bugs.kde.org/show_bug.cgi?id=509438#c0
Nothing is modified (at least, when invoked with the variable assignment prepended):
#!/usr/bin/env bash
QT_QUICK_CONTROLS_STYLE=org.kde.breeze nextcloud-desktop
QT_QUICK_CONTROLS_STYLE=org.kde.breeze does not improve the situation with me either. Still missing iconography.

QT_QPA_PLATFORMTHEME=gtk3 nextcloud doesn’t solve the issue for me. I still get missing icons.
Also I have notice similar missing icons else in KDE, for exemplar in some (but not all) KDE connect notifications. See for e.g.:
Operating System: Fedora Linux 42

Please don’t randomly override `QT_QPA_PLATFORMTHEME` unless you know what effects this will have and why exactly you should do it. It will affect a lot of things and change the behavior of your Plasma system in more ways than you expect.
