[Bug 1907300] [NEW] window resizes incorrectly across different screens

[Lorenzo Ranieri]

Public bug reported:

Hiding the details on a different screen from the one they were shown on
causes the white background of the window to appear shifted w.r.t the
border. This happens regardless of the screen it is done on and in all
phases of the update process, including when the details disappear at
the end. Moving the window on a different screen fixes the mismatch.

To reproduce:
1) launch update-manager while having updates to install;
2) click on the "Details" button to show the details;
3) move the window on a different screen;
4) click again on "Details".
