Artifacting on Nanao MS8 29FSG w/ CRT Emu Driver (SOLVED!)

(Edit: I've solved the issue! See my last post! Woohoo!)
Hi Everyone,
New user, but I've been participating over on Arcade Projects.com restoring an Astro City. Nice to meet all of you!
https://www.arcade-projects.com/forums/index.php?thread/11781-astro-city-restoration-and-monitor-fix/
So I've got CRT Emu driver working on my Nanao MS8 29FSG, but there's pretty bad artifacting on everything. Even the desktop at 320 x 240 has it. I'm using a Radeon HD 5770 with Windows 10 and a JPAC.
There's quite a lot of white spots on the right side of the pixels. It's noticeable pretty much everywhere, especially on the right side of Sakura's skirt and hair, as well as the background. I know it's not the monitor because this does not happen when I have the Neo Geo (real hardware) plugged in. The chassis and PSU have been completely recapped and fixed as well. Here's what I've tried.
Various Monitor presets, Generic, Arcade 15khz, Nanao MS9, etc. Different games, Super resolutions, original resolutions, I can't seem to figure it out.
Would I need to create a monitor preset for the Nanao MS8 29FSG? I've been doing a lot of reading on CRTs. Learning about Front Porch, Back Porch, stuff like that.
Thank you in advance! And I'll be sure to share anything I learn about the MS8 29FSG, as it doesn't seem to be a very common monitor.

The MS8 is actually a very popular monitor....just not outside of Japan.
your issue looks like a signal problem not a monitor problem....and like you say, real hardware doesn't exhibit this issue... which basically eliminates the monitor as a source.
i'd look into how your PC is connected and how the ground from the VGA cable is tied to the computer. VGA has several grounds and some cables might only use one for ground where your videocard might be expecting more. try running "nokia test" or "eizo monitor test" and see if just particular color is doing it... or if it's them all. see if there is some kind of graphics smoothing or something going on in your videocard driver.
it's not much, but it's something to start with.
BumbleChump:
Thank you! I'll definitely look into the grounds for my setup, as well as those tests you mentioned.
Will report back soon!
BumbleChump:
I've tried various things, but none of them worked. There's also a small spark sometimes when connecting the JAMMA to the computer. The grounds and video ground on JAMMA are the connections causing the spark, so I think I have a ground loop. All the equipment is ultimately grounded at the same point, so I need to figure out how to reduce or remove the ground loop.

To digress, because i have no idea what's causing your issue, the MS8's can be a little sensitive in other ways too. Lilshawn, do you have any idea if the MS8-29FSG is going to have the same issues as the one's the MS8-26SE does, that i linked to a while back?
