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

-

Mar 18, 2026

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
