How to reproduce:
1. Open attached project "Case_1267258"
2. In the Menu Bar click Test -> Crashtest
3. If the crash does not occur, repeat step 2

Reproducible with: 2018.4.26f1, 2019.4.9f1

First lines of the stack trace (2020.1.0a8 and up, OpenGLCore, OpenGLES3):

First lines of the stack trace (below 2020.1.0a8, OpenGLCore, OpenGLES3):

Notes:
1. Reproduces with OpenGLCore, OpenGLES3
2. Stack trace changes from 2020.1.0a8 when using OpenGLCore and OpenGLES3
3. Direct3D11 throws errors regarding failure to create Texture but does not crash
