Thank you @EdwardGeo for all your work in this issue, you gave new life to our dual GPU Zbook's and I learned a lot.

Saw this on the MacRumors '2011 iMac Graphics Card Upgrade' thread (might be relevant since they can also use AMD Radeon Pro WX4170 mobiles:)

WX4130/WX4150/WX4170 screen recoding (CMD+SHIFT+5):

Does not work for unknown reason on Big Sur and Monterey using these cards, but this command enables it back

me@iMac % defaults write com.apple.cmio CMIO_Unit_Input_ASC.DoNotUseOpenCL -bool true

Just found this again hidden deeply in my notes. Might work with other cards, too?

(tested on iMac12,2+WX4170 Monterey 12.3.1 OLCP 0.4.4)

Is this a problem that happens with our setup?
