Window size issues in windowed mode

[kugiigi]

Description

When in windowed mode, the window size does not follow the stored size.
Upon initial opening, the window size defaults to a certain size.
Also, when opening the settings page, the window size changes again to this certain size.

In my device, even if in windowed mode, the terminal app opens always in fullscreen mode. I cannot see how to change the size of the terminal window, as in my case it never opens in non fullscreen mode.
