DESCRIPTION I'm using deskflow with a plasma 6.6.5 client and server. When I move the mouse from the client back to the server, the mouse cursor remains on the screen on the client (it should disappear) and the error message: Libeis: 🪲 Bug: eis_device_stop_emulating: missing call to eis_device_frame() Appears in journalctl --user -u plasma-kwin_wayland -f I found https://github.com/deskflow/deskflow/issues/9423 which claims this is a kwin bug. STEPS TO REPRODUCE 1. With two plasma machines, setup deskflow 2. Move the mouse between client and server OBSERVED RESULT The mouse pointer remains visible on the client. It's not just a visual artifact, the pointer is still there, as I can see with a mouseover video preview playing in my browser. The error message also appears in the journal. EXPECTED RESULT The mouse pointer disappears from the client and there are no error messages in the journal. SOFTWARE/OS VERSIONS The hardware I have is different between client and server, but the KDE versions are identical, due to both running nixos with the same flake. The linked deskflow github issue shows this is not a nixos specific issue. Operating System: NixOS 26.05 KDE Plasma Version: 6.6.5 KDE Frameworks Version: 6.26.0 Qt Version: 6.11.0 Kernel Version: 6.18.35 (64-bit) Graphics Platform: Wayland Processors: 24 × AMD Ryzen 9 9900X 12-Core Processor Memory: 64 GiB of RAM (60.4 GiB usable) Graphics Processor 1: AMD Radeon RX 7900 GRE Graphics Processor 2: AMD Ryzen 9 9900X 12-Core Processor ADDITIONAL INFORMATION This is not an issue when the client is running x11, but the server is running wayland.
I see the tag and component of 'multiscreen'. Just to be clear, both machines have a single screen. But they're are two machines involved. I'm not sure if that's the correct tag, although I don't know exactly how you're using the tag.

Pushed by davidre into branch 'master'. plugins/eis: Do not send events from release warp to capture Before we warped the pointer and then deactivated the capture, this generated a motion event that we forwarded to the capture (but not frame which resulted in a libei bug log). Instead deactivate first and warp later before showing the cursor again.
