Multi-display setup

That is the expected/normal Framebuffer Depth for an AMD dGPU. As can be seen in the screenshot below showing my RX 6700 XT and dual 2560x1440 displays.

Funny thing I just noticed; if I apply custom wallpaper picture and not the ones from Apple's Wallpaper menu, there's no glitches. Also most Screen Savers are glitched, but not the last ones from the menu.

I will try with Ventura tomorrow and see what's the situation there. Maybe I can pinpoint the problem.

I have moved this thread to "Graphics"

Little update.

I installed Ventura on a separate SSD, same story (glitches). Did some twiddling around with EFI, removed and reinstalled GPU,...after many tweaks and restarts it's just ... "fixed"(?).
I honestly don't know what did the trick, but something did. I also copied Ventura EFI to Sonoma EFI and it's all good there too.
I then went and updated SSD with Ventura 13.6.4 to Sonoma 14.3 and everything went well. Will do some more testing over these couple of days since I'm still waiting for some PC parts. If everything's all good I will clone this SSD to M.2.

I cloned Sonoma from SSD to M.2 and did more testing.
All 5 displays are functional, ethernet, sound and bluetooth works but when I run Cinebench the CPU temps ramp up to 100°C, the AIO fans don't react. I have Lian Li Galahad II Trinity SL-INF 360, seems to be recognized by the system (System Information>USB). When I do the same test in Windows everything is functional, AIO fans rump up and keep the CPU temps down.

Any ideas what should I do?

your USB ports don't look that right

but you can create a new thread for that in desktop support

Finished the build, here are some pictures.

That looks amazing!

Well done!
