[albajr]

do you have the same problem with colver?

yes, but with Open Core the system works more quickly

Then it's not a problem of the type of EFI bootloader.
Try to upgrade all kexts to latest versions.

I managed to get rid of all graphical glitches I had on my z50-70 by changing the AAPL,ig-platform-id to 0c00160a in Mikorist's config. Seems fine to me ATM, I'll test around some more.

       <key>AAPL,ig-platform-id</key>
                <data>DAAWCg==</data>

With that AAPL,ig-platform-id I don't even have QE/CI on G50-70

but with the old one I can up VRAM to 2048 MB

I've got QE/CI working just fine with my config, so this is kinda weird.
On both configs I can use 1536MB of VRAM, but your config seems to cause glitches with thumbnails and images in chrome and steam, and screen distortion when mousing over stuff in full screen chrome, steam.
I can kinda remove the image glitches by setting framebuffer-cursor to 00009000 (9MB) but the screen distorsion/scratch effect is still there.
The only thing that made them go away completely was changing the ig-platform-id.
Maybe my config only works on other Z50-70s?
Here's what Hackintool shows with my config. I am kinda clueless when it comes to OC stuff.
