In data-heavy screens, did a Linked List ever create subtle UI glitches?

Using a linked list as the backing store for a chat timeline caused subtle UI scroll glitches. Inserts at the head were efficient, but diffing the linked list directly for UI updates required walking from the start for every index calculation, causing scroll jumps as message positions shifted. The fix was maintaining a parallel indexed array to ensure stable indices for rendering, resulting in smoother scrolling.
