Bug ID: 514845
Summary: Black folder icons when using SVG icon themes at sizes
>22px on Plasma 6 / Qt6
Classification: Plasma
Product: plasmashell
Version First 6.4.5
Reported In:
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]

Target Milestone: 1.0
I’m using Kubuntu 25 with Plasma 6 and Dolphin.
Folder icons appear completely black when using SVG icon themes
(Breeze, Papirus, etc.) at icon sizes larger than 22px.
Important details:
- The problem happens even with newly created empty folders.
- It is NOT related to previews or thumbnails.
- Changing icon size to 22px makes the icons render correctly.
- Sizes like 32px, 48px or larger show black folder icons.
- Changing icon themes does not fix the issue.
- debsums reports all related packages as OK.
- System integrity and packages are fine.
This strongly suggests a Qt6 SVG rendering issue affecting Dolphin
icon rendering at certain sizes.
Workaround:
Set icon size to 22px (PNG fallback is used).
Environment:
- Plasma 6 (Wayland)
- Dolphin
- Qt6
- Kubuntu 25
Thank you for your time and for looking into this issue.
