I updated CEF to 142 yesterday, and it looks like the stutter issue has gone away.
Could some of you who have had this issue give it a quick test to confirm?
If that is the case, that is the last thing I had on my list to do before 2.5. So I can get it released (be aware there are a couple of changes in master which are being held back for 2.6, but you are unlikely to be using those)
But there is a new issue in 2.5. (build windows from 2025/12/03)
After sending the command
PLAY 4-200 decklink device 6
Casparcg starts spewing this messages approx. 9 times per second:

I have Blackmagic drivers 14.5, two Decklink duo cards.
In 2.4.2 this command works correctly without any warning, casparcg.config files are identical in both versions.
