I changed the atom-text-editor::shadow in atom-text-editor.editor as atom's alert explain.

Now on my editor, the vertical scrollbar style is fine (as before):

where i can get this result by this selector (in the red square):

the problem is in the tree-view selector and in the search file selector:
