Reproduction steps:
1. Open the attached project "ReproProj" with the Android Platform selected
2. Build And Run on an Android device
3. Swipe your finger left and right across the screen and observe the white bar with red and blue ends moving
4. Minimize and restore the game
5. Repeat the left and right swipe finger movements
6. Observe the bar
Expected result: Bar is not jittering and continuously moves together with the finger
Actual result: Bar is jittering when swiping the finger just as seen in the JitterinReproduce.mp4

Testing environment: Windows 10 Enterprise 21H2
Notes:
- The issue is related to touch input on mobile phone screens
- The input occasionally starts to jitter, with missing delta values in certain frames, and then it becomes smooth again
- In the attached video user demonstrated a graph of the touch delta position (red line in the top right corner) and delta time below it (blue line for Time.deltaTime, green line for touch.deltaTime), after the app is minimized and restored, the graph becomes jagged, and the input starts to jitter
- Seeing black artifacts when testing Android Player built with version 2021.3.24f1 and 2023.2.0a13
