SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. open system settings, select the "shortcuts" section, then the "kwin" section. 2. select any action, e.g. "Switch one desktop down" 3. Click on "Add custom shortcut" 4. type keys Meta+e. A pop up is displayed saying "Shorcut Meta+E si already assigned to action 'Dolphin' of Dolphin. Do you want to reassign it?" 5. Click on Yes 6. In the lower right corner of system settings, click on "Apply". OBSERVED RESULT typing Meta+e does nothing, not even opening dolphin. EXPECTED RESULT When I type Meta+e, plasma switches one desktop down. SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Tumbleweed 6.3.7-1-default/5.27.6 (available in About System) KDE Plasma Version: 5.27.6 KDE Frameworks Version: 5.107.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION - If between step 5 and 6 I uncheck the Meta+Ctrl+Down default setting, and check it back, then everything works as I expect. - If I click on another section of the settings panel (e.g. "About this system") and come back to Shortcuts -> KWin, the Meta+E setting I put on "switch one desktop down" has disappeared. - If after step 6 I select the Dolphin section in the shortcuts, click on "Add custom shortcut", type Meta+e, approve the reassign, click on Apply, and type Meta+E, then Dolphin does show up. - I observed the same behavior both on my personal Fedora machine and on my work tumbleweed machine. - If I assign another shorcut that does not conflict with another shorcut, then it works as expected.
Can reproduce in Plasma 6 as well.

I can reproduce this exact behavior on Fedora 40 with Plasma 6.2.1 as well. It also seems to happen similar when importing shortcuts with overriding settings, it doesn't do it there either.

Git commit 8f3f2e2719c0459f48c65b1960368a2ab884b14a by David Redondo, on behalf of Dávid Bácskay-Nagy. Committed on 20/03/2026 at 09:25. Pushed by davidre into branch 'master'. kcm/keys: prevent shortcut conflicts during save (BUG: 471370) Fixes a bug where reassigning or swapping shortcuts could lead to temporary conflicts due to single-pass updates. Use a two-phase approach: first remove obsolete shortcuts, then apply new ones, ensuring conflict-free updates. To test: assign two actions different shortcuts, then swap them and save.
