Question Troubleshooting MSI RX570 8GB Screen Glitch

[kchipchase]

Here's my build: https://pcpartpicker.com/b/t3LJ7P

Here's my problem I can't figure out.

Everything works fine except when I have both monitors plugged in and an application goes full screen. So any game, or when using Zoom for video conferencing and a screen is shared, or something like that. When that happens, I get lots of glitching across the two screens (click link for video of problem). This glitching will continue until I disconnect one monitor. I cannot reconnect the monitor until application is closed. From time to time, I also get weird effects like fonts not displaying correctly, and pink or green text. This display problem seems random and fixes itself after a few moments.

With help from the Google machine, here are the things I've tried to fix it:

(One monitor is plugged in using an HDMI cable. The other is using a DisplayPort to HDMI cable (all in one cable...no adapter)) EDIT: Both monitors are now plugged in use identical DisplayPort to HDMI Cables. Issue Remains.

• Used a different HDMI cable.
• Plugged the DisplayPort cable into a different port on the GPU
• Uninstalled and reinstalled the Drivers from AMD's website
• Uninstalled the drivers and installed an older version of the drivers
• Used Display Driver Uninstaller to clean off the drivers and repeat the two things above.
• Changed the refresh rate on the monitors
• Changed the option on the monitor itself from "auto-detect" to manual.
• Turing FreeSync on/off
• Disabled Microsoft Error Reporting Services. Didn't fix, so I turned it back on.
• Adjust the power settings. I turned PCI Express Link State Power Management to OFF
• Checked for drivers for the monitor (I have two acer XF521Q monitors). Acer had some on their website, but when I downloaded the driver it wasn't an .exe file and I don't know what to do with the files that downloaded.

Someone suggested a power delivery issue. I have a 520W 80+ Bronze PSU. Seems like that should be enough.

Any thoughts????

Update: I tried buying a second displayport to hdmi cable, to make them both the same. No dice. Still have the issue.

UPDATE: I tried plugging the GPU cable into a different slot in my modular PSU. Problem remains. Trying to borrow a friend's GPU to test in my system and then I will also try to plug my GPU in their computer as well. Next step after that is an RMA on the GPU most likely.
