For future reference, the ram and soundcard are not that important compared to other components. Audio drivers cause more issues. Even the CPU will affect LMMS's performance more as LMMS is more CPU intensive than it is memory intensive. To nit-pick a little more, I doubt that a demo mmp would help in this case because it is a graphical glitch that from what he has said is program wide, not project specific.
I suspect that he is either using a misconfigured theme or has a corrupted install of LMMS. My 2¢
