For screenshooting in FS, you need a specialised FS-screenshooter. Else you end up with getting a shot of most of the screen, but where the instruments are you end up with black holes very often. Or other details lack, because the internal memory and the time the screenshot takes to get completed, do not work together well, the memory already is updated or deleted before the screenshot can grab all its content.
Try
fsscreen. I use it in FS2004 and FSX, and it does not produce these artifacts. Of course it also works nicely in all other contexts, not just in FS. It is simple, and has no big interface at all. Launch it before you launch FS, or tab out of the sim and launch fsscreen then. Hitting "print" key creates a screenshot in the folder where you stored the unzipped fsscreen exe. Format is bmp.
