Following some of the answers found for windows atleast.

Seems like it should be quite easy to implement, the last answer seems the most promising in regards to fullscreen handling.

Do you mean APP_DX_FAKE_FULLSCREEN?

The program acts just like a fullscreen program, it minimizes to tray when I select something on another screen, it is alot faster to switch though, but not what borderless fullscreen is, games that uses borderless fullscreen is actually a window without titlebar and no borders on the edges of the window.

Hi,

Yes, to my understanding this is how APP_DX_FAKE_FULLSCREEN works.

Please note that this gives smaller rendering performance
