Meta+shift draws unremovable red lines on screen

In addition, meta+ctrl+shift draws red arrows. On KDE plasma x11. The lines persist between desktops and activities - the only way I have found to remove them is to reboot the PC.

I would appreciate any help in getting rid of the lines without rebooting or stopping them happening in the first place.

//EDIT2: you can also change its settings when enabled, to modify the shortcut and other options.


It’s a desktop effect.

System Settings ─ Workspace → Workspace Behavior → Desktop Effects → Appearance

Deselect “Mouse Mark”.
