The mesh angle setting is a trade-off between the precision of the view, speed, and memory...
The "not following edge" is a display artifact.

The mesh angle can be changed in Options>View. So maybe try, for example 4 or 5, instead of 10.
The view should look better, but be aware that too low a mesh setting may have other detrimental side effects for the users experience,
depending upon users computer system...

Be aware that the new "guard rail" "protection/..." may cause the number to revert to 10 upon re-loading MoI.
Guard rail can be avoided, see Burr's and Michael's posts here:
