My setup:
- Macbook pro 13 inch 2017 with Touchbar
- Razer Core X
- Sapphire Nito+ Vaga 56

Trouble:
At the first time, I connect eGPU to TB 3 port (right-top) and it work just fine.
So I continue to make it work with bootcamp, and everything work fine too.
But after a lot of time reset to Windows 10, I see my built-in screen blink, external screen work fine.
I don't know when it happen, I think it start when I changed eGPU to left-bottom TB3 and disable Port #9 – 9D18 at Windows.
After disable, something go wrong so I enable it again but it not help, I think my screen start flickers from here

Now I boot in to Mac and it flickers too, I see a windows logo bleeds in the back even on macOS.
It also flickers on rEFInd boot manager screen.

Something below not help:
- I try to boot MacOS to safe mode but it not help. ( In safe mode, it flickers too)
- Reset PRAM and SMC
- Reinstall Bootcamp (Windows 10 1803)

------
Thank you for reading my situation, hope some one can help me out of this, thank you so much!!!

Does the flickering occur only when the eGPU is attached? When running a game or video on the internal display, does the flickering go away? What's the macOS version?

Flickering occur when eGPU is not attached too. I just reinstall bootcamp again and seem like it not happen when install windows.

When running a game or video on the internal display, does the flickering go away?
I feel lik e flickering decrease when have a animation show on in screen like video or when I move window around

What's the macOS version?
My macOS version is 10.13.6

I had the same issue with my 2016 MBP without Touchbar. The issue even survived some complete reinstalls. There are some people here in this forum who fixed it by turning the energy saving feature of the iGPU off which lead to flickering. But to me it didn't help. But maybe it's worth a try?

I didn't really fix the issue - for a couple of days I lived with it and after a few reinstalls (macOS and Bootcamp) it was gone. I have no clue how this exactly happens - I just can imagine some firmware error of the graphics memory. Else I'd have no idea how a Windows logo could come up in macOS.

Setup: MacBook Pro 2018 15" 2.6GHz Radeon Pro 560X on macOS 10.14 & Windows 10 (Bootcamp); Sonnet eGFX Breakaway Box 350 with a Zotac GTX1080 AMP! Edition

I have windows10 installed on an external SSD, reseting NVRAM and SMC several times didn't fix anything...but after restarting macOS several times, swapping the power and thunderbolt3-egpu cable, restarting again, changing the display setup etc etc...it got fixed...or at least it got better, initially I was able to see the windows logo flickering, then just a blink in the middle of the screen, like when the screen is set at 30hz...and now I can't see anything...maybe there's 1 frame of the 60hz displaying the windows logo and can't see it...the thing is...don't buy another macbook...the issue can be fixed

Wow this just happened to me. Freaky. Thanks Windows logo is fading slowly minutes by minutes.

I think it occured because bootcamp went into sleep mode or something. Came back to my computer and it rebooted itself and Windows was stuck in boot.

Experienced the same issue just recently.

- Razer Core X
- MBPro 13" 2xTBT 3 ports (Non-Touch Bar)
- Sapphire Vega 64
- macOS Mojave 10.14.4 / Bootcamp Windows 10 latest update as of 05/10/2019

Issue:
When I attempted to boot to Windows using bootcamp, windows boot screen froze and started glitching with lines and other anomalies. I gave it minute or two but it kept doing it. After that, I force shut down the laptop and disconnected eGPU. When I booted back to macOS Mojave, the screen started showing ghosting Windows boot logo with flicker. Ghosting / flickering persisted in recovery mode, Windows / bootcamp and other user environments.

I reached out to Razer using email support and they are taking long to answer. After searching online I discovered that it's not only Razer but other eGPU enclosures can cause the same issue. 

Apple's official support article states that "3. macOS High Sierra 10.13.4 and later don't support eGPUs in Windows using Boot Camp or when your Mac is in macOS Recovery or installing system updates." ( https://support.apple.com/en-us/HT208544 )

Cause:
This seems to be the best explanation found here at egpu.io - "When booting into an operating system that is not Mac OS, the Mac laptop’s firmware tends to deactivate the integrated GPU if there’s another GPU present. ","By only having an integrated GPU, the 13″ MacBook Pro sometimes hangs at the Windows bootup process if an external GPU is connected." - but not sure why ghosting / bleeding / flickering persists as after effect.

Resolution:
In my case ghosting / flickering slowly faded and finally disappeared after 2 hours of running computer as normal. 
As it was almost gone but still visible I booted to safe mode (Holding Shift key before boot to macOS) and it didn't show there. This made me think that I was not dealing with permanent hardware issue, rather than it was more likely system level / possibly drivers issue. 

Workaround:
Bootcamp eGPU setup guide worked for me ( https://egpu.io/bootcamp-setup-guide-tb3-macbook-pro/ )

I'm just cautious to not have eGPU plugged in directly with Bootcamp / Windows. I use apple_set_os.efi drive to boot from as described in the setup guide which allows me to boot Windows without freezing / flicker / ghosting. 

When I'm done using eGPU I make sure to shut down Windows and disconnect eGPU. I do this because setup guide requires you to set bootcamp drive as default drive, thus you never know if system unexpectedly restarts and defaults to Windows partition with eGPU plugged in, causing ghosting issues again. This way you can avoid it happening while your device is unattended.

I just had this happen with my 2016 MBP. I have seen similar behavior before. 

My attempt to fix this was making a USB intaller for macOS, wiping the whole SSD, installing macOS from scratch, and restoring from a TimeMachine backup from before the incident.

That's the only thing that would explain having the issue survive into recovery, safe mode, or Windows. For your compete reinstalls, were they from recovery mode or where they from a bootable USB?

I would just like to add that my process worked. After installing macOS from a bootable USB and restoring from a TimeMachine backup, I can report that the flickering issue is gone. I thought I saw some flicker while just using my MacBook just now, but I might just be seeing things. (It's late)

This happened to me because I was trying to get my Razer Core X to work in Bootcamp. I plugged the eGPU in at the boot picker and tried to load into Windows. I was just presented with the Windows logo with no loading indicator. I left it for a minute but gave up and force shut down realizing my mistake. I then rebooted the machine into macOS and once there I saw exactly what was Posted by: @devdevs

When I booted back to macOS Mojave, the screen started showing ghosting Windows boot logo with flicker. Ghosting / flickering persisted in recovery mode, Windows / bootcamp and other user environments.

I had experienced similar display flickering before. The last time I saw anything like this, it was caused by an issue with OneDrive on macOS. I had just finished managing a bunch of files and wanted to play some games, so I shut down and tried booting into Windows. Upon which the machine displayed some odd behavior which I don't remember. Long story short, I rebooted and macOS was now flashing a "ghost" image of a gray/black screen. The flashing did not affect Windows or Recovery mode though, it just affected macOS. I figured that this problem had to be related since the symptoms were so similar, despite the flickering occurring across the board now. 

I figured out how to fix this issue after failed attempts at reinstalling macOS from Recovery, resetting SMC/NVRAM/PRAM, etc.. I did this by making a bootable USB, formatting the entire SSD of my MacBook Pro, installing a fresh copy of macOS, and then restoring from a Time Machine backup. This method worked in fixing my previous issue, and it worked for this one too.

Something about the TimeMachine restore/backup overrides whatever firmware error that causes these flickering ghost images. I don't know what causes this issue or why my solution works, I just know that it does work.
