Reproduction steps:

1. Open the attached “SimpleCompositor” project
2. Open the “TutorialScene” scene
3. In the Project window select any asset or folder and drag it across the editor window

Expected result: Various parts of the editor window flicker
Actual result: No visible flicker

Reproducible with: 0.24.1-preview, 0.24.2-preview (2020.3.41f1, 2021.3.13f1, 2022.1.22f1, 2022.2.0b14, 2023.1.0a18)

Note: flicker mostly prevails on the Scene/Game view but ultimately happens on the whole window randomly. The same behavior could be reproduced if dragging objects from the Hierarchy.
