”A VisualElement must not allocate more than 65535 vertices” error appears when trying to draw a map with "Painter2D"

-

How to reproduce:
1. Open the user’s attached “WorldMapBug.zip” project
2. Open Menu > Tools > World Map - Too Many Vertices - Bug
3. Observe the Console window

Expected result: No errors
Actual result: Error “A VisualElement must not allocate more than 65535 vertices” appears

Reproducible with: 2022.2.4f1, 2023.1.0b1
Could not test with: 2020.3.44f1, 2021.3.17f1 (“Painter2D” not available)

Reproduced on: macOS 12.4 (Intel)

Note: Error saying "A VisualElement must not allocate more than 65535 vertices" but the map only contains 10500 vertices

  1. Resolution Note:

    When using the Painter2D to draw straight lines, more geometry is required than the positions provided to LineTo. The line has a thickness, which requires at least 4 vertices, and each joins and caps between line segments generates extra geometry as well. An easy way to work around this issue is to split the drawing in mulltiple VisualElements (each VisualElement has a 65k vertex limit, but there's no hard limit on the number of VisualElements).
