Opening and closing the Shader Graph window causes a memory leak
Reproduction steps:
1. Open the attached project
2. Open Task Manager to monitor RAM consumption, note current RAM consumption
3. Open TestGraph from the Assets folder
4. Close the Shader Graph window
5. Repeat steps 3 and 4 ten times
6. Observe RAM consumption in Task Manager
Expected result: Memory consumption stays the same
Actual result: 300-500 MB added to memory consumption
Reproducible with: 10.9.0 (2020.3.36f1), 12.1.7 (2021.3.6f1), 13.1.8 (2022.1.8f1), 14.0.3 (2022.2.0b1), 15.0.0 (2023.1.0a3)
Reproduced on: Windows 10
Note: Each cycle of opening/closing the Shader Graph window consumes about 30-50 MB of RAM

Resolution Note (fix version 2023.1.0a22):
The shader graph window was not properly disposing of its view/visual element resources. Thank you for reporting this issue and bringing it to our attention. We now are disposing of the memory allocated by the view and this leads to fewer memory leaks. There is more work that can be done here to further reduce the amount of leaked memory and left over garbage, and this will be addressed in the future.
