Middle of screen not updating correctly in 4K. Guest - MacOS High Sierra 10.13.5

Description
The screen does not update correctly once the full screen resolution is set beyond 2560x1440(x32).
Resolution set using: <ExtraDataItem name="VBoxInternal2/EfiGraphicsResolution" value="3840x2160"/>
Once the mouse moves beyond about X1100 only every 8th pixel updates. Then after about X1800 it works again. So the mouse seems to disappear in this vertical band.
Refreshing the screen by toggling out of full screen and then back updates everything correctly. In my mind that points to the guest screen buffer being filled correctly. However, it seems the buffer isn't always copied to KDE.
Guest: MacOS High Sierra Version 10.13.5. 256MB VRAM, 8GB RAM
Host: F27, KDE 5.12.5, Frameworks 5.46.0, Qt 5.9.4, Kernel 4.16.13-200.fc27.x86-64 8 x Intel Xeon CPU E3-1245 v5 @3.5GHz, 32GB Ram, NVidia GForce GTX1060 6GB, Driver 390.59
Windows10 guest @ 4K runs fine. Fedora27, Oracle EL7.5, Centos..... all fine.

- It's usually better and faster, if issues get first addressed in the VirtualBox forums. More than 95% of the issues are resolved over there, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of.
- You were supposed to follow these steps when you filed the bug, and provide a VBox.log:
Attach a (full) log file ("Machine" menu/"Show Log" in the main VirtualBox Manager window) straight away to save time for you and for us. The log file contains a lot of useful information about both the host and the guest systems as well as information about what happened during a particular machine run. Please do not cut and paste it.

You opened a ticket for a Hackintosh?
OSX guests are only supported on Apple hardware (which you do not have). See: Mac OS X guest on a Windows Host.
This ticket should be closed as [Invalid].

Thanks,
Please close and remove this ticket. I'll move this to my macbook pro.

FYI
Exported to OVA and imported on MacBook Pro.
Works perfectly in 3840x2160 4K.
Cheers

So, I guess it's the Hackintosh that fails. Nothing of value is lost, nothing to worry about...
Photo because screenshot is good (rather large - 4K curved screen)
