--- Comment #1 from David Chmelik <dchme...@gmail.com> --- SUMMARY I use Slackware64-current 15+ GNU/Linux (up-to-date n86) with KDE Plasma 6 (KDEP6) packages though unofficial for testing, many people use the set. When I go/run 'systemsettings -> appearance & style -> colors & themes -> colors' and select another standard theme it shows 'applied' (button text grays) but nothing happens: I select Dolphin (normally changes colours), and exited & restarted Konsole (normally changes colours after restart), but neither changes colours. I can also test FreeBSD 14-stable UNIX (after updating on n86), maybe Devuan 5.01-stable (Debian 12 with SysVInit) or Gentoo 2025-7-n later. STEPS TO REPRODUCE 1. Upgrade KDEP5 to 6. 2. Change standard colour theme such as from Breeze Dark to Breeze Light. 3. Close & reopen everything (systemsettings, Konsole, Dolphin). OBSERVED RESULT No longer changes colour theme. EXPECTED RESULT Change colour theme. SOFTWARE/OS VERSIONS GNU/Linux/KDE Plasma: Slackware64-current 15+ GNU/Linux (n86) / KDEP6.4.2 KDE Plasma Version: 6.4.2 KDE Frameworks Version: 6.15.0 Qt Version: 6.9.1 ADDITIONAL INFORMATION This has been happening since something such as KDEP6.4.1 or 6.1 or earlier (whenever Lucky Cyborg started packaging). Though most else still does what it should, due to severity of affecting user experience (UE) I'll have to immediately switch back to KDEP5 and (also due to some tens of minutes process uninstalling & downgrading/reinstalling); may not get to test much unless a specific test might speed debugging up, but if known by weekend/Friday, I plan to test then. -- You are receiving this mail because: You are watching all bug changes.
