    On Centos 7.4/7.5 Unity crashes when either launching with -force-vulkan or switching to vulkan only graphics API in the editor.

    Code (CSharp):
    1. 2018.3.0b12/Editor/Unity -force-vulkan
    Machine running Unity does not have internet access so cannot run the submit bug tool.

    From unity log:
    Code (CSharp):

    We did a quick check here on CentOS 7.5 and were unable to reproduce this. What version of the driver do you have installed and graphics card are you using? Is it possible you can submit us a minimal reproducible case via the bug reporter on a machine that does have internet access?

    Also, just to manage expectations, we don't officially support CentOS right now, so if this turns out to be a CentOS-specific issue then we may decide not to fix it. However, we're still interested in a bug report in case this is a bug in our Vulkan implementation or if it's something we can help you work around.

    Attaching editor log

    I add vulkan lib to LD_LIBRARY_PATH and launch Unity like this:
    /unity_install/2018.3.0b12/Editor/Unity -force-vulkan
