AMD Radeon Navi GPU

Man, I’ve had issues with my Gigabyte 5700 xt since 10.15.2. I think I’ve noticed/had freezing more then others because I’m using multiple 4K screens. It’s been a gong show so far. 10.15.4 is practically unusable for me when working in audio/video apps.

I had those freezing issues too. They hapended rarely but regularly. What fixed it for me was going to the bios setting and disabling everything related to PCIe power saving.
 
Does anyone have drm working in Safari on 10.15.4 and AMD 5700?

Yep Netflix works. Use iMacPro1,1 smbios for best compatibility.

Is everything as smooth as it was on 10.15.3 for you? I have pretty much the same hardware as you and the experience I get with this update is that everything is just unusable. I mean, acceleration is there, the dock stays fixed while it is rebooting. Going through the dock icons is laggy and also launchpad super stuttering skipping frames. The videos play fine but selecting anything on the browser and the GUI is a laggy mess. Am I the only one experiencing this?

With Clover 5109 updated Lilu, Whatevergreen, ALC, got blackscreen after boot.
Reverted to Clover 5108 But with updated kexts everything works as expected.

It's a Clover problem?

It's not I'm afraid. Well, at least not for me. I am using the iMac 19,1 SMBIOS, I doubt that will be the problem. I am back on 10.15.3 and its as smooth as butter.
I have never had an update as bad as that
