Remove the jamb in the windows theme?

Question

Windows

Good afternoon, in a simplified theme (I'm very used to it), in chrome such sides appeared

In the usual theme, there are no such jambs. Maybe someone knows how to fix it?

Answer 1

If the problem is not in changing the screen resolution and not in changing the scale in the browser, then this is probably a bug, and it is better to write about it to the developers.
