Making progress overall but found a problem that I'm not having much luck googling other than it's probably a dsdt issue.

So I've got a Lenovo Ideabook 320-15IKB with Intel UHD Graphics 620. I've got most things working right now as best as I can tell. I need to do some more with the USB ports, HDMI out, and audio but, basic wifi, bluetooth, brightness, power management, and battery display are taken care of.

However, when the computer goes to sleep it will wake up with a garbled screen. The only thing I found was some people talking about a similar issue in Lion being caused from needing a DSDT patch but I can't find anything more current on where I need to start looking in the DSDT. Any help on where to start reading would be appreciated.

Running 10.13.3
