Different issue in Chrome scroll, probably not related. Win 10,32 bit,any of last dozens of updates to chrome if that matters. Open chrome. Left mouse click All Bookmarks. Tap up arrow key to scroll to the bottom of long list. Begin to slide mouse down off All Bookmarks into that list to get to the bottom of that list. And the list of bookmarks vertically scrolls a few or half a dozen lines so the last few or half dozen lines are now hidden. But, giving them credit, they did fix an introduced behavior where deleting a bookmark or moving a bookmark into a bookmark folder would repaint the whole bookmark list and scroll you back to the top of the list. That has now been fixed and the list of bookmarks no longer scrolls when I move or delete a bookmark. Thank you for that.
