Created attachment 179759 [details] Demo of the issue SUMMARY When you open a KCM which has a middle column showing sub-categories, the font used for the title above this list of sub-categories is smaller than the font used for the pane to the right. This looks odd to my eyes. STEPS TO REPRODUCE 1. Open System Settings 2. Choose a category like Mouse & Touchpad OBSERVED RESULT The words "Mouse & Touchpad" near the top of the screen are in a smaller font than the word "Mouse" to their right. EXPECTED RESULT The words "Mouse & Touchpad" near the top of the screen are in the same size font as the word "Mouse" to their right. SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20250324 KDE Plasma Version: 6.3.3 KDE Frameworks Version: 6.12.0 Qt Version: 6.8.2 Kernel Version: 6.13.7-1-default (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION The "Users" KCM, which uses a similar middle column (although it is a column of users rather than of sub-categories), does *not* demonstrate this issue and looks better, to my eyes.
In this case it's intentional. We've gone back and forth on the font size here; there are complicated and non-obvious trade-offs. The current state is what we deem to be the least bad option. :)
Thanks for the info. Is the problem to do with how it might appear in different (more verbose) languages? I can see that might be a problem, but ellipses exist... The Application Permissions KCM (0:23 in the video) looks particularly odd with the different font sizes for "Application Permissions", "Flatpak Applications" and "Permissions" titles. I wouldn't mind "Flatpak Applications" and "Permissions" being smaller to match "Application Permissions", rather than "Application Permissions" being larger, if that's better! Can you point me at previous discussions regarding this?
There have been a number of discussions over the years in multiple places; not sure I can find them. But the TL;DR version is this: Cons of using a normal level 1 header text size: - Text gets elided easily with many languages - Header visually competes with the page header to the right Cons of using a smaller header text size (status quo): - Visual inconsistency with other multi-column, multi-header views
