Hi. I setup a fresh desktop with Ubuntu, with all graphics driver needed. The editor does not start, and even if it starts somewhy, when I hit play, it crashes. I tried it with the latest Ubuntu and CentOS 7.
- If I use windows, it works of course.
- If I run the editor with -opengl4, it works
So it looks like, something vulkan related.
Here is the crash report:

Here is the log, if I start it from the command line:
