SUMMARY The "Fall Apart" desktop effect is triggered too loose (for too many cases). STEPS TO REPRODUCE 1. Boot KDE Neon. 2. Go to System Settings -> Desktop Effects. 3. Enable the "Fall Apart" one and click Apply. 4. Logout and login from KDE Neon. 5. Drag some windows to the left, top, right margin of the screen and release the mouse button so they snap OBSERVED RESULT 1. The effect is triggered for both logout and login animation. 2. The effect is triggered for all the windows snapping / tiling / maximizing. EXPECTED RESULT The effect should be triggered just for windows that are closed normally or abnormally (killed programs too if possible). SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 6.2.90 KDE Frameworks Version: 6.11.0 Qt Version: 6.8.1 Kernel Version: 6.8.0-51-generic (64-bit) Graphics Platform: Wayland ADDITIONAL INFORMATION Hardware: Laptop Dell Inspiron 5770 Graphics Processor 1: Mesa Intel® UHD Graphics 620 (main) Graphics Processor 2: AMD Radeon R5 M465 Series Not sure how this FIXED bug report is similar to mine of it it's any help: https://bugs.kde.org/show_bug.cgi?id=405971 This FIXED (both in status and last comment) bug report, says that it should not occur anymore, but it does (at least for me): https://bugs.kde.org/show_bug.cgi?id=444166 And if we had a similar cool effect like "Fall Apart" for closing windows, then it would be fine / nice to use the current "Fall Apart" effect for programs that had crashed or have been killed, like this bug report I think it suggests: https://bugs.kde.org/show_bug.cgi?id=475475 It would make more sense and it would be more intuitive to understand what just happened to some program. But since there's no other nice effect similar to this one, I prefer to use this one for normally closing windows. Warning: Do no try to snap windows to screen corners with this effect enabled as will make Plasma freeze completely! I'll write another bug report about that soon.
And here's the bug with the Plasma session freezing, when this effect is on and windows are dragged towards and outwards of the screen corners: https://bugs.kde.org/show_bug.cgi?id=498849
I can reproduce it triggering when dismissing the logout screen. Cannot reproduce for window tiling/snapping/maximizing actions.
