[GPU PLM] Total bake time is 5x slower when moving Scene viewpoint during the bake
Steps to repro:
1. Open the attached project;
2. Open Test Runner window (Window>General>Test Runner);
3. In the Test Runner window expand SmokeTests section;
4. In the Test Runner window double-click on SmokeTests_SceneViewCameraTest test;
5. Observe the test execution time.
Actual result:
Test execution time is extremely slow. On the current test station it takes around 10 minutes to execute.
Regression introduced in Version 2022.2.0a9.
Expected result:
Test execution time is around 2 minutes (Version 2022.2.0a7).
Notes:
- Reproducible in Version 2022.2.0a9;

Resolution Note (2022.2.X):
This is by design. The issue is only reproducible when Progressive Updates are enabled. We have recently made this functionality more safe by making rendering and compositing jobs happen in lockstep instead of in parallel. This would prevent from having more potential bugs and crashes. Therefore, this slowdown is expected and this is fully justified by the Progressive Updates feature itself. Workaround is to disable Progressive Updates and rebake.
