I think if the team are shipping it in this state then either: they don't have the ability to notice the issues on the core team, or they see the issues and ship it anyway. Feedback like this is unlikely to solve either of those cases.
This isn't complex stuff either. I'm not a designer, I don't even do frontend/UI work, I'm basically just a backend engineer. If I'm spotting this stuff on first glance at the main marketing screenshot, which should be the best possible case, then this stuff must be glaringly obvious and pervasive.
You might have a particularly good eye. I saw none of these problems in the marketing screenshot.
I only see one ... icon in the entire screenshot, nothing is fuzzy, and all text looks aligned. The only weirdness is a misalignment between the sidebar header and the main window header, but those don't need to be aligned anyway.
