I've checked with different cable, problem still occurs, occasional blank screen glitch only happens at 3840x2160 and 1920x1080 HiDPI mode, any lower or higher resolution works well or when I'm connecting secondary 720p monitor to the HDMI port surprisingly 3840x2160 and 1920x1080 HiDPI mode works well in my 4K main monitor..





Hi, sorry a bit OOT, assuming the HD630 is fully accelerated with quick sync enabled in your system working in tandem with your RX460 what's your Bruce X FCPX test result? No one shared RX460 bruce X test yet. thanks

downgrade to clover 4049 version, solve same problem with me.
 

Follow this guid, everything is ok except wake from sleep. And there is some glitch at menubar, two dot line sit on icons, anyone can help?

motherboard: GA-B250N phoenix-wifi
CPU: intel i5 750
no discrete graphics card

I set DVMT-prealloc to 64MB, is that correct?

Looks fine, but 128mb might be better.
And you might want to use something other than MAX for DVMT-size.

I also have a Gigabyte GA-B250N Phoenix-WIFI with a 7400 and I get the same upper right corruption when when I login and when leaving a fullscreen application such as Safari.

I'm currently using High Sierra but the corruption also happened in Sierra (10.12.6).

I have tried multiple DVMT settings. These logs were exported using DVMT-prealloc = 128MB and 128MB for DVMT-size. I tried almost all DVMT settings, like setting the prealloc to 1024MB. I'm also using the latest versions of lilu and intelgraphicsfixup.

Any help is appreciated!

Why do you have OsxAptioFixDrv-64.efi *AND* OsxAptioFix2Drv-64.efi?
Those two files are mutually exclusive.
Use only one (and try both).
Remove CsmVideoDxe-64.efi.
Try without Shiki.kext.
iMac18,1 may be a better choice.
You need to rename HECI->IMEI.

Are all your kexts installed to the system volume?

Changing to iMac18,1 fixed it. I could have sworn I tried that before...
I ended up also removing OsxAptioFix2Drv-64.efi and Shiki.kext (quicksync appears to be working without it).
All my kexts are on the EFI partition kexts/other.

Thanks for your help!

Rolled back to Sierra 10.12.6 and the glitches appeared again. This only works on High Sierra (choosing iMac 18.1).
On High Sierra, when I choose iMac 18,1 smbios, I get no glitches except when I shutdown or restart. The screen fades out and then changes to a solid turquoise colour until it shuts off.
