Top 6 C++ ScreenShot Projects

I used to really like this software, and I still do. But there were a couple of dealbreakers for me.
1) As others mentioned, Wayland support. But it seems that it's gotten a lot better since I last used it. I resisted using Wayland for a long time because of several software breaking, but I've switched over now that most of the things I use now work (or because I've stopped using things that don't work).
2) it was broken for me with fractional scaling. This is the main reason why I switched, I started using fractional scaling on my second monitor and could not properly fix it for the life of me. I haven't tested it recently, but I just checked, and the github issue seems to still be open. https://github.com/flameshot-org/flameshot/issues/564

InjectableGenericCameraSystem
This is a generic camera system to be used as the base for cameras for taking screenshots within games. The main purpose of the system is to hijack the in-game 3D camera by overwriting values in its camera structure with our own values so we can control where the camera is located, it's pitch/yaw/roll values, its FoV and the camera's look vector.
