Hello,
Have anyone experienced issue with CasparCG client, when mixer tools aren’t working with 4k@60p resolution, all options are grayed out, soon as I change to different resolution all options are available.
Transform settings which are made on different resolution like 4k@30p can be applied.
Client version used: 2.0.8 and 2.2.0
Yes I experienced similar issues during my testing with the 8k Pro Card. See here: Decklink 8k pro
This behaviour is still present in 2.3.3.
I couldn’t find any open issue about this specifically on github, just some brief mentions. I guess there is not that many people using ccg for 4k50/60.
It’s because the format is not in the database off the client.
it can be changed easily with a database editor
you can find it in
C:\Users\username\.CasparCG\Client
which is a hiddenfolder soo don’t forget the point 
offcoarse this should be fixed in source
