The UI Toolkit renders UI elements incorrectly when using a linear colour space within the built Player



Reproduction steps:
1. Open the attached project “ReproProject”
2. Dock the UI Builder Window (navigate to Window > UI Toolkit > UI Builder)
3. Build the project
4. Contrast the UI appearance between the Player and the UI Builder Window/Game View

Expected result: The UI is rendered with low contrast
Actual result: The UI rendered appears brighter

Reproducible with: 2021.3.37f1, 2022.3.25f1, 2023.2.19f1, 6000.0.0b15

Reproduced on: Windows 11 23H2 (22631.3007), macOS 14.3.1 23D60 Darwin 23.3.0 (user’s)
Not reproduced on: No other environment tested

Note: Also, reproducible on Android

  1. Resolution Note (fix version 6000.0.3f1):

    A workaround has been implemented that will allow the UI to be rendered in gamma color space to a UNORM render texture.
