We have simple scalability settings in our project, where the user can change the resolution scaling etc via a graphics options menu. This worked perfectly in both Editor and Packaged game in 4.12.
When we moved to 4.14 however, the resolution scale value now seems to range from 100 > 10 in editor, while ranging from 0.1 > 1 in packaged game. The Window mode is also always displayed as ‘Windowed’, regardless of the editors actual window mode.
