Editor crashes at "__assert_fail_base.cold" when opening a project (Linux)

Linux

-

How to reproduce:
1. Create and open a new project
2. Observe the crash

Reproducible with: 2019.4.31f1, 2020.3.21f1, 2021.1.27f1, 2021.2.0f1, 2022.1.0a12

Notes:
1. Reproducible on Ubuntu 20.04 and 18.04
2. Not reproducible on Windows 10
3. Likely caused by running Mesa driver versions 21.0.0 and newer and using the OpenGL graphics API
4. Does not reproduce on Nvidia GPUs

  1. Resolution Note (fix version 2022.2):

    Currently, we are still investigating this issue. At the moment, these options are available for people experiencing this crash:
    - Waiting for the fix to land;
    - Switching to an OS that does not reproduce this issue (macOS and Windows);
    - Installing a dedicated GPU on your system (not possible for those using a laptop);
    - Downgrading Mesa drivers to be older than version 21.0.0.

    Additionally, some people have reported that forcing Unity to run with the -force-vulkan flag bypasses the crash.

    The crash is caused by a bug in the MESA drivers. There's already a fix in progress (https://gitlab.freedesktop.org/xorg/lib/libx11/-/merge_requests/113) and currently, it's waiting to land in the main MESA branch.

    I managed to get around this error by making sure I was using proprietary nvidia drivers and rebooting.

    The problem that's probably causing this issue are told in 3. Some Mesa graphics drivers could be responsible for this. I also run Ubuntu but on version 21.10. In fact it's Kubuntu. I installed the editor on my external HDD. First time I launch the editors it crashes. It always does. I can't recognise the problem.

    As I understood from the clarification on the problem, the solution would be to install the official drivers from nvidia, i guess..
    y/n ?
