Description:
Closing LibreOffice with a copy of large range of cells on the clipboard (from
a 47KB sized file) triggers a 5 GB ram spike on close
Steps to Reproduce:
1. Open attachment 139120 (bug 117997) (file-size 47 KB!)
2. Open a process monitoring tool showing ram usage
3. Download https://www.nirsoft.net/utils/insideclipboard.zip (or some other
clipboard viewer)
3. Select the range A1:ACQ114
4. CTRL+C
5. CTRL+Q -> See RAM usage pike at 5 GB and combined with high CPU usage
6. Launch inside clipboard to inspect the content
Actual Results:
* Insane amount of ram used for a 47 KB file
* Information is added to the clipboard in a plethora of formats including
Windows Bitmap (714 MB) & CF_DIB (714 MB). Necessary?
Expected Results:
* No massive ram spike
* Is it necessary to add a Bitmap of the sheet to the clipboard? Even twice;
using different formats?
