SUMMARY In Present Windows/Overview, if you drag a window using both touchscreen and touchpad (maybe mouse also works), the window glitches and the whole interface is unresponsive. After a while the screen goes blank. Alt + Space won't open KRunner in this case. A coredump doesn't generate and nothing shows up within KDE Crashed Processes Viewer, so a crash report isn't available. But the issue is reliably reproducible. STEPS TO REPRODUCE 1. Use a laptop with touchscreen 2. Use KDE Plasma Wayland session 3. Open any window (openSUSE's Welcome page in my case) 4. Activate Present Windows effect 5. Drag that window using both touchscreen and touchpad OBSERVED RESULT The dragged window glitches, the whole interface is unresponsive. After a while the whole screen goes blank. Alt + Space doesn't open KRunner. TTY console is still accessible. EXPECTED RESULT The dragged window should follow either touchscreen input or touchpad input (given a stable priority), without halting the whole interface. SOFTWARE/OS VERSIONS Linux/KDE Plasma: (available in About System) KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.110.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION Wayland session. Intel Graphics. Microsoft Surface device.
Can you attach a phone recording of what happens so we can be 100% clear that we understand the issue? Thanks!

Got it, thanks. This was a bug that was just fixed for Plasma 6 with a total rewrite of the effects. I can confirm it works now.
