[GUIDE] Resolve boot screen garble

No its supposed to resolve the fact that the Apple logo will appear distorted half-way through boot and sometimes appears as "teared" due to resolution change.

A red screen during boot-up is definitely a fully different issue.
Try using the CSM video driver in clover to set a graphics different mode on bootup, it might resolve your situation.

Is there a non-clover version of this fix?

Yes, you can decode the Clover replacements into their original hex strings.

As a perl patch this would turn into:
Code:
# Run the following commands in order to patch IOGraphicsFamily to resolve bootup graphics glitches
sudo perl -i.bak -pe 's|\x85\xc0\x74\x5d\x48|\x31\xc0\x74\x5b\x48|sg' /System/Library/Extensions/IOGraphicsFamily.kext
sudo perl -pe 's|\x41\x88\xc4\xeb\x03|\x41\x88\xc4\xeb\x23|sg' /System/Library/Extensions/IOGraphicsFamily.kext
Please confirm if this works and I will update it in the first post.

i tried the clover patch. it fixed the boot issue but caused smearing/tearing of windows when dragging them.

Maromi,

Double check if QE/CI is still active in OS X. Your case sounds like de-activation of graphics acceleration, which should not be caused by this patch.

Try different ig-platform-id values. (you're currently using 0a260000).
