My biggest issue with GDevelop has been and is how it handles fullscreen for native games. It seems to default to stretching everything to fill the screen. So, I would like to see better fullscreen handling. Simply keeping the aspect ratio and filling the empty space with the window color would work for most of my own cases, but it would also be nice if it could change the camera size to the native aspect ratio. But personally, I can easily accept letterboxing.
This way, I could develop in one ratio and it would still work on displays with different aspect ratios.
I’ve been trying to make this work on my own for quite some time using camera settings, but I still can’t seem to make it work right.
