I previously posted
<http://nabble.documentfoundation.org/Pasting-plain-text-into-Calc-changes-row-height-and-undo-doesn-t-revert-td4086328.html>
about an issue with row height, but the problem is even more basic than I
realized at the time. Pasting isn't required at all to trigger it. This is
still in a vanilla install of LibreOffice v 4.1.3.2 installed via
PortableApps.com in Windows 7 Home Premium x64
Create a new spreadsheet. Already there's a problem: row #1 has height 0.17"
with "Default value" unchecked. All other rows (presumably) have height
0.18" with "Default value" checked.
You can now perform one of a variety of innocuous operations and the row
height inexplicably changes. Examples:
* Enter a character, say "x", in cell A2 and press Enter. Row height is
unchanged. Enter the same character in cell A2 and press Enter again. Row
height is unchanged. Perform an Undo operation (reverting A2 content from
"x" to "x") -- row height changes to 0.17" with "Default value" unchecked.
* Select cell A3, and click Format > Change Case > lowercase -- row height
changes to 0.17" with "Default value" unchecked.
I'm sure there are many more examples.
