Hi. They are this.
Found it on --> https://software.broadinstitute.org/software/igv/AlignmentData
Downsampled reads areas are marked with a black rectangle just under the coverage track. The coverage track represents coverage for all the reads.
If you wanna get rid of the, go to preferences and turn off downsampling.

No I do not mean the vertical cursor bar, but the horizontal black segments right between the reads and the coverage track.

looks like a rendering glitch maybe? sometimes insertions are shown in that area (purple triangles)
