Please help me understand why this UI change upgraded 0.4 losec to 0.5 hisec:
Furthermore please explain why it requires, even in compact mode, about 15 to 20% more screen estate than before. Even the overview window in compact mode features spaces between tabs that cram the content needlessly into even scarcer space - same with the chat window and maybe others as well.
All the buttons got bigger and scaling is now more of an issue - please remember that you are not designing UI for a touch interface! 
Also, why did you not pick up on previous feedback provided to you weeks in advance, such as here and here?
Other, non critical feedback would consider the rather unpolished appearance, such as here
and here
and here
The amount of blur also screams a bit “mobile game” which is not realy my cup of tea but it’s not mission critical.
Also the right click menu opens way too far to the right relative to cursor position.
