U can use libs with sabre by setting the merge method override to 0 in any gcam modregarding AGC (v8)
Not sure if this is already known, but I found out a way to use Arcide libs - the ones that use Sabre - without crashing after taking a picture.
All you gotta do is enable the Fix for RAW16 merge in Advanced settings

Only the build number should be the same like: 8.4 libs for 8.4 gcam.
