Comparison screenshot
Here is the comparison on how it renders here at 125% (top part) vs your screenshot (bottom part) the separator is still brighter but less. note that the separator between columns is stronger than the one of the scrollbar by design, to tell that the scrollbar belongs to the left panel, if the two separators would be identical it would actually be an usability problem.
The issue is that sometimes they get too much different, i guess indeed due to fractional scaling: in both screenshots you can see lines that become two dimmed pixels because they are rendering still not quite aligned to the pixel grid
the vertical separator however should definitely have the same color of the header separator A possibly relevant merge request was started @ https://invent.kde.org/frameworks/kirigami/-/merge_requests/1937 A possibly relevant merge request was started @ https://invent.kde.org/frameworks/kcmutils/-/merge_requests/278 A possibly relevant merge request was started @ https://invent.kde.org/plasma/systemsettings/-/merge_requests/377 |
Created attachment 185580 [details] White lines STEPS TO REPRODUCE 1. Use Breeze Dark color scheme 2. Set scale factor to 160% or 175% 3. Launch System Settings OBSERVED RESULT The line separating sidebar and content view is visibly brighter than other separator lines. See attached screenshot EXPECTED RESULT Same color as other lines ADDITIONAL INFORMATION Doesn't seem to be a general Kirigami issue, as I can only reproduce it in System Settings SOFTWARE/OS VERSIONS Operating System: KDE Linux 2025-09-25 KDE Plasma Version: 6.5.80 KDE Frameworks Version: 6.20.0 Qt Version: 6.9.2 Kernel Version: 6.16.8-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 7840U w/ Radeon™ 780M Graphics Memory: 16 GiB of RAM (14.9 GiB usable) Graphics Processor: AMD Radeon 780M Graphics
