Memory leak when continuously resizing the Editor window

Window management

-

How to reproduce:
1. Create a new project
2. Resize the editor window, while doing it inspect the CPU and GPU memory usage

Expected result: memory usage doesn't increase
Actual result: CPU and GPU memory usage increase

Reproducible with: 2019.4.37f1, 2020.3.30f1, 2021.1.28f1, 2021.2.18f1, 2022.1.0b14, 2022.2.0a9

  1. Resolution Note (2022.1.X):

    This appears to be a bug in Windows 10 Task Manager, which incorrectly display the Dedicated GPU Memory counters:
    https://docs.microsoft.com/en-us/troubleshoot/windows-client/performance/gpu-process-memory-counters-report-wrong-value

    Using a proper profiling tool, i.e. PIX for Windows, shows no evidence of a memory leak when resizing Editor windows. Please do not rely upon Task Manager to provide accurate performance data. If you suspect a memory leak or some other performance issue, please use a real profiling tool to capture and analyze the problem.
