How to reproduce:
1. Create and open a new project
2. Open the Task Manager
3. Create a Cube in the Hierarchy
4. Select the Cube in the Hierarchy or the Scene view
5. Observe the Task Manager

Expected result: The GPU utilization stays at ~0%
Actual result: The GPU utilization fluctuates between 20-30%

Reproducible in: 6000.0.20f1, 6000.0.23f1
Not reproducible in: 2021.3.44f1, 2022.3.50f1, 6000.0.19f1

Reproduced on: Windows 11 Pro (23H2), macOS (M2) Sonoma 14.4.1
Not reproduced on: No other environment tested

Notes:
- When testing locally on a macOS machine, before reproduction, the GPU Utilization fluctuated ~6-8%, after reproduction, it increased and stabilized at 57%
- I suspect this is reproducible on any machine
- Moving the Cube results in less GPU utilization
- In version 6000.0.19f1, when nothing is selected GPU utilization fluctuates between 8-12%, after selecting the Cube, it stays the same, while in version 6000.0.20f1, the GPU utilization is at 0% when nothing is selected. This could indicate that the performance fix is likely what caused the regression
