I have two calc files built from the same source, and formatted generally the same. But from A1 onward, they display heights slightly differently, and widths noticeably so. This is to the point where manually wrapped text, copied and pasted in full (selected by column and not cell) do not display the same way. Even the UI has slight discrepancies (The function Sigma shifts slightly, for example.)
If you alternate between the two from A1, it looks like a mild shift. By column H, the same content does not fill the area equally (visible on row 29.) If you look at the AB-AI page, the same content is off by an entire cell.
Zoom, formatting, column widths and row heights are all equal. Default formatting are the same. If I accidentally changed a setting, I haven’t been able to figure it out - although I can assume it would be in the S1-Test file, as it is the one acting out of sync compared to several files using the same formatting. For the test files, I made sure to copy and paste the entire column range of A to AI inclusive to eliminate any obvious editing mistakes I might have missed.
