Bug Reporter Window Resizing Is Visually Glitchy and Jitters Unexpectedly

Unity: Bugreporter

6.2.X

6.1.X

During the resizing, the window is constantly re-drawn, layout re-calculated and resizing animations are triggered.

Steps to reproduce:

Create a new Unity project
Navigate to Help > Report a Bug…
Attempt to resize the Bug Reporter window by clicking and dragging its edges or corners
Observe the visual behaviour during the resizing process

Actual results: Resizing the Bug Reporter window is visually flaky; the UI snaps, jitters, or behaves inconsistently

Expected results: Resizing should be smooth and responsive

Reproducible with versions: 6000.1.0f1, 6000.2.0a9

*Can't reproduce with: 2022.3.61f, 6000.0.47f1 (Using old Bug Reporter)

Tested on (OS): macOS 15.5 (Silicon M4)
