Left is incorrect scale, right is expected result.

When launching a fullscreen (xwayland?) application on a 2x scaled Wayland session, the application will render at native resolution then be upscaled, making only a corner of the application visible. 

This is most apparent in games, applications such as Firefox or VLC are not affected.
