scaling of ChartViews is wrong when SaveAnimation sets ImageResolution

I find it totally frustrating that ParaView cannot save a complete layout, scaling each view appropriately when specifying an ImageResolution that is different than the screen layout. The two images attached say it all. One image was saved in batch mode, resulting in over-stretched legends, titles and axis, while the same can be done from a ParaView client after careful (and many iterations) setting of the overall screen size.

I use SaveAnimation('/tmp/foo.png', layout, ImageResolution=[1280, 800])

any hint to make this full-proof would be greatly appreciated.
