C70 XFAVC .MXF Flicker in Premiere

There appears to be a software bug that has been recently introduced that causes .MXF footage to flicker in the Source monitor, Timeline playback, and in even in the exported file. It seems to be an issue related only to MXF files coming from the C70.

It almost seems like it's enabling/disabling a lumetri color effect even when no effect is applied and is very random across clips with the only constant appearling to be that the affected clips are all .MXF files. Any other codecs are unaffected. Project files older than a week or two ago seem to have no issues.

I will be transcoding all raw footage into ProRes upon ingest untill this issue is resolved.  

See attached video files as an example.
