That's a limitation of glfw/platform from the older days. When a window goes fullscreen, it gets "exclusive" access to desktop and nothing else is rendered.

The workaround I use is to resize the window to width - 1 and height - 1 where width and height are dimensions of the screen. This keeps the window just less than fullscreen dimensions to not trigger the black screen.

Thank you for your fast response! That is the solution I have just tried a few minutes ago and it is working

Also mouse position handling is not wrong, I just had to set window pos to 0,0

Where have you learned this info from? :)

@FreePhoenix888 mostly from search results when I was debugging this issue in the past https://devblogs.microsoft.com/directx/demystifying-full-screen-optimizations/ . fullscreen transparent window should give you a few google results.

The workaround was good enough for my use case, so I never bothered going further. Fullscreen also messes with always on top order flag, so the workaround was pretty much the only way forward.
