I have created an atlas in which the page orientation (horizontal / vertical) depends on the geometry of the covering vector (@atlas_geometry);
exporting to pdf I get the expected result, while exporting as an image (PNG) I get some resized images; I attach screenshots

[layouts] Fix data defined page sizes sometimes lead to incorrect
created atlas image sizes

Because the exporter prefers to use the image size when it's
specified (as is done in QGIS app), we need to ignore this
when the aspect ratio of that size doesn't match the aspect
ratio of the page to render.
