Regression
No
A lot of "TMP.GenerateText" calls when enabling and disabling "Canvas" Component
Reproduction steps:
1. Open the attached “repro_IN-49860.zip“ project
2. Open the Profiler (Window > Analysis > Profiler)
3. Press the “Record profiling information (F9)“ button
4. Enter the Play Mode
5. While in Play Mode, disable and enable the “Canvas“ Component in the “Canvas“ GameObject
6. Observe the Profiler
Expected result: No spikes in performance
Actual result: There's a big spike in performance under “CanvasUpdate.PreRender” due to a great amount of “TMP.GenerateText” calls
Reproduced with: 3.2.0-pre.1, 3.2.0-pre.5 (2021.3.29f1), 4.0.0-pre.2 (2022.3.7f1, 2023.1.8f1, 2023.2.0b4)

This happens again in Unity 2022.3.39f1
CanvasUpdate.PreRender
TMP.GenerateText is called for multiple Text Mesh Textes when disabling the canvas / when setting a canvas group alpha to 0 and interactable to false.
