I can reproduce the what is happening in your image. However, to make sure that this is an issue it would help greatly if you could provide a screen shot of your setting in the details panel as well as a screen shot of the positioning of your assets within the canvas panel.
i got similar issue. The screen position and render translation is not exactly the same. The render translation need to be multiplied by a factor depending on current display resolution to produce correct result.
640x480 → multiply by 2.25
1280x960 → multiply by 1.25
the formula for that factor is something like: 1080/min(resx, resy)
