This will be a bit difficult to explain. First off (as any Windoze dev should know, methinks) windows has hit-areas for the mouse / touch. Some windows have at least two different hit-areas; the NC hit area and the client hit area.
The NC (non-client) hit area is for example the title bar of an windows application. When a window is displayed behind another window the application is not “activated” or “shown”. In order to activate a Brave-window using the mouse i need to click somewhere in the window.
Now to my problem; when i drag the mouse cursor over a non-activated brave window the titlebar changes from “solid” to containing the search-control. When my brave-window is a bit narrower (x-length) than usual, the areas i can click “safely” are almost non-existent. By safely i mean to click somewhere that does not activate any child-windows and/or controls but only brave itself. Using Brave on a laptop with a trackpad is almost impossible. Each time i want to activate another brave window i accidentally click on a button, the search control or inside a page (potentially navigating from that page if a link gets hit. Also, note, that using a trackpad the precision of the mouse pointer is bad (when /i/ use it, that is) and after a days work i have back pains because i tried too many times to put the mouse exactly on the edge of brave-windows.
Now; i do not think that i have been able to make myself understood 
but a solution to my frustration is to not fade over to the search-control in the title-area as long as the brave main-window is not activated. Then i would always be able to click almost anywhere on the title-bar to activate Brave.
