Hi @fifoosid ,

There are several issues which might need to be adjusted.

• The glow/shadow of warning, error, etc. has a color. The grey is for the default state
• When you hover on input the bottom border is shifted a bit, so there's a 1px of white below
• The border of the active state of (Multi)ComboBox is a bit broken on the edges/rounded corners.

P.S. Considering list (items) in the ComboBox, SuggestionsPopover, etc., as well as Popover, is not in the scope of this change

Cheers

Yes, changes related to Popover(already merged) and ListItem will not be part of this change
