Screenshot taken with split view containing a spreadsheetview is wrongly framed and has wrong resolution
To reproduce, load some data, split the view, create a spreadsheet view, and frame the data nicely in one render view.
Select the render view and go to File > Save Screenshot.
Enter a file name and hit OK. Note now that the views shift to the left and reduce in size.
Retain the default resolution and such and hit OK. The resulting image has a reduced size, and parts have been clipped out of the image.
Edit: We first noticed this in 5.8.1. This bug was not present in 5.6.3.
