During the rendering of images in the 2D case the images are resampled to fill the whole world geometry area. This leads to problems due to origin shifts. A possible solution is to set the "in plane resample extent by geometry" to true but this leads to resampling artefacts.
To avoid this the images should not be resampled in the 2D case and instead simply rendered. Since this leads to preformance issues it should be possible to disable this behavior.
