My machine is thinkpad x1 yoga 2018 , uhd620 , WQHD resolution , with macos 10.14.6 installed.
My efi patch seems to have some problems related improper graphic patch.
1. The screen sometimes have flickers , especially on safari browser.
2. Sometimes kernel panic happens after wake from sleep , black screen then reboot.
3. I cannot enable specific resolution(1920*1080) in hidpi , using hackintool or FixEDID+DarwinDumper
