Mouse lock for trackball mode

[parkerlreed]

Is your feature request related to a problem? Please describe. Currently, when trackball mode is enabled, the drag interaction is limited by the window/screen bounds.

Describe the solution you'd like Mouse lock when trackball mode is enabled, enabling continuous movement with a trackball/mouse, not limited by the bounds of the container.

Describe alternatives you've considered Tried looking for something in KDE Plasma/Gamescope that could do this but seemingly nothing exists.

Additional context Was thinking possibly a relative mouse capture similar to how games handle mouse input.

Contribution Can help test but wouldn't know where to start in implementing.
