Updated over the weekend from 14.4 to 14.5. Everything went smooth, but I get the purple lines on Apple logo screen. My monitor flashes twice and then my video is visible. I also lost use of my on-board video, which is the HD 530. It was working fine with 14.4 but does not work in 14.5. I currently have to use the AMD video card, RX 560. Other than that, all is ok.

Anyone else experience loosing on-board video, and if so, any solutions yet?

I have almost the same configuration as you except Vega64. The same effect, I lost HW 530 support in 10.14.5:(
