A red warning box appears on launch that says:
A fatal error has occurred and X cannot recover
Shader::Compile(tag.f) '0(612) : error C0151 EOF inside comment`
Version: 4.30 - Code revision 254587
Please inform EGOSOFT GmbH technical support
I had just done an update when this started occurring so it could be related to an X11 update, an Nvidia update, or a steam update (all of those updated). I tried uninstalling and reinstalling but that did not fix the issue.
I am running on Fedora 32 with proprietary Nvidia drivers.
