Did you enable CSM/legacy boot?

Post ioreg as ZIP: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

What is the issue?

Sorry for reply late.

I'm sure that I enable CSM/legacy boot.

Download patchmatic: https://bitbucket.org/RehabMan/os-x-maciasl-patchmatic/downloads/RehabMan-patchmatic-2015-0107.zip
Extract the 'patchmatic' binary from the ZIP. Copy it to /usr/bin, such that you have the binary at /usr/bin/patchmatic.

In terminal,

if [ -d ~/Downloads/RehabMan ]; then rm -R ~/Downloads/RehabMan; fi
mkdir ~/Downloads/RehabMan
cd ~/Downloads/RehabMan
patchmatic -extract

Note: It is easier if you use copy/paste instead of typing the commands manually.

Post contents of Downloads/RehabMan directory (as ZIP).

Also, post ioreg: http://www.tonymacx86.com/audio/58368-guide-how-make-copy-ioreg.html. Please, use the IORegistryExplorer v2.1 attached to the post! DO NOT reply with an ioreg from any other version of IORegistryExplorer.app.

And output from:

kextstat|grep -y acpiplat
kextstat|grep -y appleintelcpu
kextstat|grep -y applelpc

Also, post EFI/Clover folder as ZIP (press F4 at main Clover screen before collecting). Please eliminate 'themes' directory, especially if you have an overabundance of themes installed.

Also post output of:

sudo touch /System/Library/Extensions && sudo kextcache -u /

No need to patch AppleIntelBDWGraphicsFramebuffer.kext on disk. If needed (should set DVMT-prealloc instead), you can do it with config.plist.

If you're trying to get rid of the glitch, try different GUI/ScreenResolution (eg. 1024x768 might help).

Keep in mind that the glitch fix only fixes it partially. You may still have a momentary glitch. It is not unexpected.

You clearly have the patch disabled. Look carefully at the screen shots you provided.

Use a plist editor to edit config.plist, never a text editor.

Disabled patches are covered in guide post #2: http://www.tonymacx86.com/el-capita...de-booting-os-x-installer-laptops-clover.html
