OpenCore 0.7 DisplayPort intermittent "No Signal" or black screen w/ movable cursor - Catalina 10.15

I'm on OpenCore 0.7 with latest kexts for WE/Lilu, and every now and then my DP will turn black, or show 'No Signal' or it'll turn black with the cursor still visible in the middle.

I'm on a Z390 MOBO (Asus TUF Z390 Pro) with Intel UHD 630, GA is working.
