Basic Linux functionality

I understand Linux as a development platform is not a priority, but if we can’t get something as basic as lighting to build, why even declare UE5 can run on Linux?

I think there should be at least some testing for basic functionality before pushing updates. I’m trying to use ue5 for archviz and I won’t be needing 95% of its features. I think it’s reasonable to ask for a functioning build where one can have a scene with some meshes and static lighting and basic blueprints working.
