Develop at Fit zoom shows a small glitch on the bottom edge of a LR-made panorama.  The glitch appears at zooms of 25% and smaller but disappears at zooms 33% and larger. Disabling the GPU has no effect. The glitch doesn't appear in Library Loupe at any zoom. LR 10.4 / Mac OS 11.6. 

Here's the offending DNG:
