Bug ID: 171260
Summary: Calc randomly pastes cell content as OLE object
instead of cell data (Ctrl+C / Ctrl+V within Calc)
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc

3 cells to copy paste, result one picture instead of 3 cells
When copying and pasting cells within LibreOffice Calc using Ctrl+C / Ctrl+V,
the paste operation randomly inserts an OLE object containing the copied
cell(s) instead of simply pasting the cell content into the destination cell.
This happens approximately 50% of the time, in a completely unpredictable
manner: the exact same sequence of actions (Ctrl+C then Ctrl+V on the same
cells) will sometimes paste correctly and sometimes insert an OLE object.
Steps to reproduce:
Open any spreadsheet in LibreOffice Calc
Select one or more cells
Press Ctrl+C
Select the destination cell
Press Ctrl+V
Observe: sometimes the content is pasted correctly, sometimes an OLE object is
inserted instead
Expected behavior:
The cell content (value, formula, or text) should always be pasted as cell data
into the destination cell.
Actual behavior:
Approximately 50% of the time, an OLE object is inserted instead of the cell
content. The behavior is random and cannot be consistently reproduced or
avoided.
Environment:
OS: Windows 10 Build 19045
LibreOffice version: 25.8.5.2 (X86_64)
UI render: Skia/Raster; VCL: win
Locale: fr-FR
Troubleshooting steps already performed — none resolved the issue:
Disabled Skia hardware acceleration (Tools → Options → LibreOffice → View): no
change
Reset LibreOffice user profile (deleted/renamed registrymodifications.xcu in
%appdata%\LibreOffice\4\user): no change
Disabled Windows 10 clipboard history (Settings → System → Clipboard →
Clipboard history: OFF): no change
Checked for third-party clipboard managers: none installed or running
Upgraded LibreOffice from version 7.5.0.3 to 25.8.5.2: no change, bug persists
across versions
Tested Ctrl+Insert instead of Ctrl+C: this appears to work more reliably, which
suggests the issue is related to how LibreOffice handles the Ctrl+C clipboard
write operation specifically
Additional notes:
This bug has been reported by many users across Windows, Linux, and macOS over
several years (see related threads:
ask.libreoffice.org/t/how-to-stop-calc-pasting-copied-cells-as-images/47947 and
forum.mxlinux.org/viewtopic.php?t=86767). Other spreadsheet applications
(OnlyOffice, SoftMaker FreeOffice) handling the same .xlsx format do not
exhibit this behavior, which suggests the root cause lies within LibreOffice's
clipboard handling code rather than the OS clipboard infrastructure.
