Bug ID: 523472
Summary: Visual Regression: Asynchronous folder emblem overlays
cause noticeable two-step pop-in layout shift in
Dolphin
Classification: Applications
Product: dolphin
Version First unspecified
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR

DESCRIPTION
Since updating to KDE Plasma 6.7, a prominent visual rendering regression
occurs whenever opening Dolphin on Home.
Standard XDG user directory emblems (such as the Documents symbol, Downloads
arrow, Music note, etc.) render with a distinct visual delay after the base
folder icon has already appeared. This creates a staggered, two-step "pop-in"
effect across all folders containing overlay emblems.
This behavior is highly reproducible and occurs regardless of the active icon
theme, global theme, or Linux distribution, indicating a structural shift in
how icon overlay layers are synchronized during the rendering pipeline pass.
Reproduced on Fedora, CachyOS, OPENSuse Tumbleweed.
STEPS TO REPRODUCE
1. Open Dolphin to the Home directory containing standard XDG user directories
(Documents, Downloads, Pictures).
2. Observe the initial render of the folders.
OBSERVED RESULT
The generic base folder graphic paints onto the screen first. A fraction of a
second later, the overlay symbol/emblem pops into existence over the base
folder. This asynchronous rendering order causes a jarring layout shift/stutter
that breaks the visual polish of the desktop environment.
EXPECTED RESULT
The folder base graphic and its corresponding emblem overlay should be
atomic—composited or synchronized to display simultaneously so that the folder
appears fully formed in a single paint event.
SOFTWARE/OS VERSIONS
Operating System (available in the Info Center app, or by running `kinfo` in a
terminal window): Fedora Linux 44
KDE Plasma Version: 6.7.3
KDE Frameworks Version:
Qt Version: 6.28.0
ADDITIONAL INFORMATION
- This issue was not present prior to Plasma 6.7.
- Tested across multiple distributions with identical results, confirming it is
an upstream framework pipeline regression.
- Toggling file/folder previews off does not affect this emblem pop-in delay.
- The visual artifact happens with multiple independent icon packs (Breeze,
Papirus, etc.), proving it is decoupled from asset styling.
Thank you.
