The plataform that I`m using is not so good with high DPI displays. But there is a way to make it work.
Right click at the ScreenToGif.exe > Properties > Compatibility tab > Disable display scalling on high DPI settings.
(A window should pop up and warning you about this while running this program for the first time on a high DPI display, not sure if it is working ;D )
