How to reproduce:
1. Open the attached “IN-150176” project
2. Go to “Edit” → “Project Settings” → “XR Plug-in Management” → “Project Validation”
3. Move “Project Settings” window around
Actual result: “Project Settings” window lags while moving
Expected result: “Project Settings” window moves smoothly
Reproducible with: 2.3.0 (6000.0.0f1), 2.6.0 (6000.6.0b9), 6.0.0 (6000.7.0a2, 6000.7.0a6)
Reproducible on: Windows 11
Not reproducible on: No other environments tested
Notes:
- In task manager ram usage by Unity Editor went from 5GB to ~15GB max
- In profiler you can see convertRuleTOBuildValidationRule is a major culprit
- When moving “Project Settings” window around try to touch it to the sides of the screen
- Looking around in the scene view also lags when Project Validation is open
