Bug ID: 486462
Summary: Fractional Scaling affects the wallpaper, making it
look blurry even when sized 1:1 with the monitor
Classification: Plasma
Product: plasmashell
Version: 6.0.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: Image Wallpaper
Assignee: plasma-b...@kde.org
Reporter: max...@directbox.com
CC: notm...@gmail.com, qydwhotm...@gmail.com
Target Milestone: 1.0
Created attachment 169107
--> https://bugs.kde.org/attachment.cgi?id=169107&action=edit
2x Zoomed comparison between 100% and 150% scaling
SUMMARY
The wallpaper looks slightly blurry when using fractional scaling, even when it
has the same resolution as the screen. This might be because the image is
scaled up with the system scale only to be resized again to fit the screen.
STEPS TO REPRODUCE
1. Use a wallpaper with clear lines/edges
2. Set the system scale to a non-integer value
OBSERVED RESULT
The wallpaper looks blurry because it is unnecessarily resized
EXPECTED RESULT
The wallpaper is displayed as-is, unaffected by the system scale
SOFTWARE/OS VERSIONS
Linux: Fedora Kinoite 40.20240429.0
KDE Plasma Version: 6.0.4
KDE Frameworks Version: 6.1.0
Qt Version: 6.7.0
ADDITIONAL INFORMATION
That the wallpaper is scaled with the system scale becomes especially obvious
when using the "centered" positioning mode for the wallpaper. Even though the
image should fit the screen perfectly, it is sized up according to the system
scale factor.
