Created attachment 453158 [details] simple HTML (+inline JS/CSS) repro of bug When an input is repositioned within a grid layout e.g. from `grid-column: 1` to `grid-column: 3`, it "leaves behind" part of its top/bottom borders in the original location until something else triggers a more thorough repaint. I did not try other scenarios [inputs moving in other types of layout, other types of elements moving in a grid layout…] but did distill the original issue we were seeing into a simple test case, attached.

Unable to reproduce on Safari Technology Preview 233. @Karl - if not reproducing for you as well, I think we can close it.
