In specific circumstances, dragging information is unstable

[bai-chi-xing]

During my usage of NOVA, I discovered an issue of unstable dragging behavior and found a practical method to reproduce it. The video includes the complete process of reproducing the problem (which may involve extra steps as I haven't fully understood the cause of the error). The version used is NOVA 2.0.0.

Due to file size limitations, I compressed it into a zip file using the LZMA compression method.

Do you still see the issues if try making these changes:

1. Change the Drag Threshold on the draggable objects very small, something like:

2. Add an Interactable component to the "Root" UI Block

What I suspect is happening is two-fold:

1. Those drag threshold values (for technical reasons) are in degrees, and that window object uses a drag threshold of 0.5 on the top bar. Because your FOV is 2 degrees, surpassing the drag threshold will require a mouse translation of roughly 1/4 your screen at that setting. That's why it appears to get "stuck" - you technically haven't dragged far enough to trigger the gesture.
2. The UIBlock3D is interactable, and the raycast intersection point is jumping between the UIBlock3D and the ScreenSpace plane. When it intersects with the UIBlock3D, the Window jumps with it. Adding an Interactable to the "Root" will basically ensure the drag position is coplanar with the window.

The second method is effective. I have a UI in world space, which caused the problem to occur. By enabling the Interactable on the Root during OnHover and disabling it during OnUnhover, I have solved the problem. Thank you for your help!
