Created attachment 171588 [details] solid vs gradient, buggy vs correct SUMMARY Some of the newer (or rewritten) KDE applications don't support the Oxygen theme, default in the KDE 4 line and still shipped with KDE Plasma, properly. When this theme is used, Qt windows should have gradient backgrounds to prettily match the window bar. STEPS TO REPRODUCE 1. Enable the Oxygen window theme in System settings > Colors & Themes > Application Style 2. Run Spectacle, Skanpage, Elisa… or just restart System settings. OBSERVED RESULT A solid gray color is used for the background. EXPECTED RESULT A gradient matching the window title bar should be used for the background. SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Tumbleweed (available in About System) KDE Plasma Version: 6.1.1 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.2 ADDITIONAL INFORMATION The problem doesn't exist in external (non-KDE) Qt applications (LXQt or other) unless they decide to use their own theming independent from the system-wide one. Maybe this is related to the new Kirigami framework, but I am not sure.
Still a thing in KDE Frameworks 6.6.
…and in 6.7.0…
Yes, we know. No need to keep bumping this bug report, which generates email spam for everyone CCd. You'll know when it's fixed because it will get marked as RESOLVED FIXED.

I just hope it won't end up among bugs reported and confirmed in the 2010s or even 2000s, but not fixed :(. (Still, huge thanks to everyone fixing any bugs in KDE).
You're welcome. But it will be fixed when someone fixes it. Annoying the developers by causing their already-overflowing inboxes to get more un-actionable email can only slow down that process, not speed it up.
