Incorrect overlaps fixed in 2023.2.0a7 The max vertex count limit issue is being worked on internally on another ticket. For now, stroking with plain colors can allow for many more line segments to be rendered correctly

Incorrect overlaps fixed in 2023.1.0b9 The max vertex count limit issue is being worked on internally on another ticket. For now, stroking with plain colors can allow for many more line segments to be rendered correctly

Incorrect overlaps fixed in 2022.2.12f1 The max vertex count limit issue is being worked on internally on another ticket. For now, stroking with plain colors can allow for many more line segments to be rendered correctly

Reproduction steps:
1. Open the “IN_31287_Painter2D“ project
2. Open the “SampleScene” scene
3. Enter Play Mode
4. Move the cursor in circles until the line count in Console reaches 1000

Expected result: previous lines did not disappear, and new lines are drawn correctly
Actual result: parts of previous lines disappeared, and new lines are drawn incorrectly

Reproduced in: 2022.2.7f1, 2023.2.0b3, 2023.1.0a2
Could not test in: 2020.3.45f1, 2021.3.19f1 (no Painter2D)

Reproduced using: macOS 13.0.1 (Intel), Windows 10 (by reporter)

Notes:
1. The number of lines from which the issue starts occurring seems to be affected by cursor speed (i.e. it takes fewer lines to reproduce when moving the cursor faster)
2. Also reproduced in Standalone Player
