I don't have any Pi machines, but if you're trying to run the screensaver on a Raspberry Pi machine, odds are that there is not enough graphics available to do so.

Usually when the Show Graphics button is greyed-out means the app doesn't have/support graphics. The last time I ran the stock BRP4 app I don't recall it supporting graphics. The optimized BRP4 app and the arm64 FGRP5 apps don't support graphics either.
As for the amount of GPU memory on a Pi, you can set that at boot time on a Raspberry Pi by running the raspi-config program and adjusting it. The more memory you give to the GPU means less available for programs to use. You'll need to reboot after setting it for it to take effect. I don't think you'll see any difference with a larger amount of memory allocated to the GPU. I run my Pi's headless (no screen or keyboard) so I reduce it to the minimum, which is 16MB.
