Quick look red glitch (Updated from Catalina to Monetary) SMBIOS related?

Hi, my current machine has been updated from Catalina to Monetary, OC 0.9.9. Hardware i7 8700K coffee lake CPU, Vega 64, MSI Z70Pro Mobo. I'm getting a red glitch on using quick look. Quick look works but I didn't have the glitch until I updated to Monetary. I am using Imac Pro 1,1 SMBIOS. Igpu or multi-monitor mode in BIOS is disabled. Should I maybe be using Imac 19,1 instead? I have full H.264 & HEVC encoding available as shown in VideoProc. I normally have reduce transparency option in Accessibility turned on, if I turn this off the glitch is much less noticeable, almost like there isn't enough time to see it. Has anyone come across this before?
