SUMMARY STEPS TO REPRODUCE 1. Login to Plasma with X11 2. Lock the screen 3. Press Escape OBSERVED RESULT Screen flickers multiple times very quickly, sometimes shows the desktop screen for a frame or two but mostly flickers EXPECTED RESULT Should be a smooth fade in and fade out which does work for me on Wayland but not on X11 SOFTWARE/OS VERSIONS Windows: macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: Manjaro KDE KDE Plasma Version: 6.3.6 KDE Frameworks Version: 6.18.0 Qt Version: 6.9.2 ADDITIONAL INFORMATION Fresh install of Manjaro KDE that has been downloaded today (as of Oct 5th), locking my screen and pressing Esc makes my screen flicker/go black quickly instead of fading in and out, I can still put in my password to log back in I tried downgrading kscreenlocker, libkscreen and kscreen (only kscreenlocker kept working after downgrading, doing it to kscreen only bricked it) I looked for solutions on the internet both by hand and with AI when I felt like all hope was lost, tried changing the Plasma theme and it did nothing, disabling the compositor did nothing, downgrading kscreen to 6.0.0 had the screen lock work but pressing Esc still brought the same issues. Only peripherals plugged in are a BT mouse since I'm on a laptop. Keyboard layout is AZERTY. (Didn't know what more info to give out, I will gladly provide more)
Thank you for the bug report! However Plasma 6.3.6 no longer receives updates or maintenance from KDE; active versions are 6.4 or newer. Please upgrade to an active version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one. If you need help with Plasma 6.3.6, please contact your distribution, who bears the responsibility of providing help for older releases that are no longer receiving updates from KDE. If you can reproduce the issue after upgrading to an active version, feel free to re-open this bug report.
Yes, I upgraded and the problem still persists even though I have versions 6.4
