Size Of Content Is Bigger Than Actual App Window Size In Modern Apps

Experiencing problem with the modern apps, where the content of the app is bigger than the actual app window, so it is impossible to use it, because the controls (buttons, input fields, scrollbars are not visible)?

Resizing of the app does not work, as the content is still bigger (its wrongly resizing with the window). Even maximized app is still unusable.

It occurs mainly in the Skype, Mail, People or Calendar apps. As you can see on the Skype screenshot, as soon as app starts it shifts the skype logo to the right, and the whole content is shifted as well.

You can also see the shift bellow, as the Options menu is partially hidden as well.

Skype is impossible to use, because the text input field on bottom is not visible.
