If you implement [four-column layout](https://github.com/openjdk/jdk/pull/23324#issuecomment-3008593168): check mark / bullet, icon, text, accelerator, it would work. Just like the text of **MenuItem1** and **JCheckBoxMenuItem 3** would be aligned to the text of other menu items.

Probably you missed seeing it but already _5-column layout_ is implemented via [MenuItemLayoutHelper.layoutMenuItem.](https://github.com/openjdk/jdk/blob/ecd2d83096a1fea7d5086736306770bcffa4fdb6/src/java.desktop/share/classes/sun/swing/MenuItemLayoutHelper.java#L464-L476)
 In the PR. `WindowsMenuItemUI.paintMenuItem` calls `MenuItemLayoutHelper.layoutMenuItem` to layout in 5 columns actually through
check icon + icon + text + accelerator text + arrow icon layout
via `paintCheckIcon, paintIcon, paintText, paintAccText and paintArrowIcon` call in `WindowsMenuItemUI.paintMenuItem` 

seems like offset value used in WindowsIconFactory paintIcon is not matching with MenuItemLayout expectation and wrong rendering is happening at slightly off position
