NTSC or PAL TOS?

as you could read it somewhere on this forum, the Atari ST core does not achieve "exact timings" required to get some "tricky" Atari ST code to work correctly (lots of demo stuff are messed up).
Most emulators are able to get exact timings because they are "full software" implementations, and so it is possible to easily synchronize differents "virtual" components. This is more difficult in a FPGA, where some real clock signals are created and used, as there are some constraints on frequencies to get an exact one.
This is probably the reason of your graphic glitches. I regularly use the Atari ST core, and there are lots of them.
Hope this could helps,
