Reproduction steps:
1. Open the attached “IN-88277” project
2. Open the “SampleScene”
3. In the Hierarchy window, select the “Spline” GameObject
4. Press “F” to focus on it (to find it in the Scene view)
5. In the top-left corner toolbar of the Scene window, select the top button to switch the “Active Context” to “Spline”
6. Move around in the Scene view
7. Observe the Scene view

Expected result: The Spline looks normal and stays in its place
Actual result: The Spline is distorted and jumps around

This problem also happens when using a simple script with: 
Handles.DrawAAPolyLine(2, points);

Lines get distorted as soon as the object is moved to positions in the distance (>1000 or 5000 units).

Reproducible on: Windows 11
Not reproducible on: No other environments tested

Note: The further away the Spline is, the more distorted it becomes. This starts happening at ~15.000 units in any direction
