This issue is caused by an error in the OpenGL ES driver on Mali-based hardware, specifically with `glUniform4fv` errornously handling uniform location conflicts. According to the GPU manufacturer, a fix has been implemented in their driver, however, given the nature of driver updates in the Android ecosystem, their fix may not be availble on all devices.

Cancelling this 2023.2 tech release issue since the support for this release has come to end of life. Cancelling this 2023.2 port case does not affect any LTS or Unity 6 Beta/Preview that remain open.

This Unity version will no longer be receiving patch updates.
