FCP Viewer Image Reversed and Inverted

I never saw this before !  Opened FCP which loaded the last used library and project that used BRAW footage from Black Magic cameras. Since I had previously relocated the footage the typical "Missing BRAW Files" appeared - which is normal and what I'd expect.  However, the viewer showed this error message inverted and reversed.  I rebooted and trashed preferences and the issue was corrected.  iMac Pro - FCP 10.6.5 - Ventura 13.3.1 - Just thought it was odd.
