Lighting Search window lags/stutters when scrolling with a lot of Lights in the Hierarchy

Unity: Search

For the time being I will close it. I will add the following explanation to the bug Fast Scrolling with UIToolkit on a vitualized container with a LOT of children is often bad for performance. So many UItk controls need to be rebound that it makes stuttering happen. This is an unfortunately expected behavior for now.

Steps to reproduce:

Create a new project using Universal 3D template
In the Hierarchy, duplicate the "Directional Light" until there are around 70 GameObjects in the Scene
Go to Window > Rendering > Lighting Search
Make sure Table View is active
Scroll in the Lighting Search window
Observe the scrolling smoothness

Actual results: Scrolling stutters and feels laggy compared to when Grid or List views are used

Expected results: Scrolling is smooth, like in Grid or List views

Reproducible with versions: 6000.5.0a9, 6000.6.0a1

Can’t test with versions: 6000.3.11f1, 6000.4.1f1 (Lighting Search window not available)

Tested on (OS): Windows 11
