[Backport] [Linux] Editor crashes at "GfxDeviceGLES::DrawBuffersBatchMode" when entering Play Mode in the LEGO tutorial



How to reproduce:
1. Open the user attached project (My
2. Make sure the "LEGO tutorial" scene is open
3. Enter Play Mode
4. Observe the crash

Reproducible with: 2021.3.2f1
Not reproducible on: 2022.1.0f1, 2022.2.0a12
Couldn't test with: 2019.4.38f1, 2020.3.34f1 (Compiler errors due to the tutorial project and its packages being incompatible with the used version)

Reproducible on Ubuntu 20.04
Not reproducible on Windows 10

Note: the project also crashes on 2022.2.0a12 but there is no stacktrace and since the issue is not reproducible on 2022.1.0f1 which indicates that that is likely a different bug

Last five lines of the crash stacktrace:

    By adding "-force-vulkan" as a command line argument for a project, I was able to run my project without Unity crashing.
    Seems that this issue is related to:
    Although, I'm using official Nvidia drivers and not mesa drivers.

    I have a project with just a few simple materials that crash with the same error, with: 2021.3.8f1, and 2021.3.11f1. Ubuntu 22.04.1.
    I have reported the issue(IN-18856) but by bug report has been closed and marked as a duplicate of this one.
    Looks that this is the same issue:

    The other one is marked as resolved: "Fixed in 2022.2.0a17".
    I don't understand how such basic problem is not being fixed for 6 months already. It's making Unity 2021.3 unusable with Linux. Does Unity give up on Linux support?
