This may be intentional, but it's non-obvious: when trying to work on pixel art/assets, with "Force pixel alignment" and "Move by whole pixels" enabled, having "Snapping" enabled as well often leads to half pixel coordinates when pasting pixel content and when moving items/layers/elements with the mouse. If this is intentional, it should be made visually clearer somehow. Otherwise, even when snapping is enabled, the coordinates should still honour pixel alignment/whole pixels.
screenshots: in the pixel font only example, dragging the layer with the mouse moves it in whole and half pixel steps, despite the "move by whole pixels". in the paperboy example, copy/pasting a pixel layer of 45x34px on a 150x150px document pastes it at the center, resulting in half pixel coordinates. again, it should honour the "force pixel alignment" here.
