MouseMotion event never occurs

[nebocco]

Hello. I'm new to Bevy and I need your help.

When I ran examples/input/mouse_input_events.rs in the v0.11.3 branch, the CursorMoved event occurs every frame, but I never got a MouseMotion event. I want to implement a feature to change the camera's orientation by dragging the screen, so I'd like to use MouseMotion.delta if able. Is there anyone had encountered a similar situation?

I suspect that it might be because I'm using a trackball instead of a mouse, and I plan to try it out soon after purchasing one.

Relevant system information

• OS: Windows 10 (Ubuntu 22.4.2 LTS on WSL2)
• Bevy feature: wayland
• Mouse: trackball (KeyBall 44)
