                OS: All
            Status: UNCONFIRMED
          Keywords: perf
          Severity: normal

Created attachment 175028
  --> https://bugs.documentfoundation.org/attachment.cgi?id=175028&action=edit
A fixed-height wrapping cell with 140000 character string

The attachment contains a single cell with a long (140000 char) string; the
cell is formatted to wrap, and the row is set to fixed height.

It takes long to open the file, or to select the cell. Possibly this could be
optimized somehow?

It looks similar to tdf#144513, but seems to be different, not blocking at
TextEngine::CreateLines. This time it spends time at ImpEditEngine::FormatDoc.
