And for me, as stated before, the issue occurs without any 3rd party .luts. I'd be fine with using the standard included camera patch if it worked, even though i'd rather use a third party one.
Just to elaborate on the issue a bit, i find it interesting that this would theoretically cause an issue. The included camera patches are just regular .itx and .cube files, like any other 3rd party .lut, with similiar file sizes. And even though i greatly appreciate you, J. Simon, taking the time to help out - im kind of on the fence on this one even if it did work.
