When Component markings are made on a Module or Device Panel background, there may be very minor mis-alignment when displayed on the tablet/touch screen, if the whole device panel has been scaled down to fit.
This is because backgrounds are a single image, whilst Components are individual images placed on top of the background. The scaling of the images can result in images sitting on pixel boundaries, resulting in a 0.5 pixel error that in 99% of cases won't be noticeable.
To avoid this problem, include any Component markings on the actual Component Background State.
