Added a new windowed mode that lets you play the game in a resizable window in case transparency doesn't work and you don't want to play in full screen mode.
Use the launch command: -windowed
The game UI will remain inside the window while you resize it.
This method bypasses the win32 api so should work in every instance but there will be a border on the window as a result.
Hope this helps! ːsteamhappyː
