OpenGL⁠ support in LibreOffice has been in constant improvement since version 4.3 (thanks to work by Markus Mohrhard, Tomaž Vajngerl, Zolnai Tamás, and others) and with that, users may experience crashes in LibreOffice, so we are providing the following information to assist them with such crashes. LibreOffice can be run with old versions of OpenGL, but the recommended minimum OpenGL version that will perform well is version 2.1, while the recommended OpenGL version is 3.3 or higher.

How to enable/disable OpenGL

Go to Tools ▸ Options ▸ LibreOffice ▸ View (LibreOffice ▸ Preferences ▸ LibreOffice ▸ View on macOS) and on the right side, check/uncheck Use hardware acceleration

Get your computer's OpenGL information

When reporting bugs related to OpenGL, it is useful to include your system's graphics card information.

Linux / BSD

On unix-like systems like Linux and FreeBSD, open a terminal through the application menu or through the desktop context menu and type in the following command

glxinfo | grep OpenGL

It should output something like this

OpenGL vendor string: Intel Open Source Technology Center
OpenGL renderer string: Mesa DRI Intel(R) 945GM 
OpenGL version string: 1.4 Mesa 10.1.0
OpenGL extensions:

Windows

On Windows XP or higher, download and install the OpenGL Extensions Viewer. Open the viewer through the Start menu and click on the Report link in the Task pane on the left. Details of which OpenGL versions are supported and the percentage of that support will be listed along with summary details of your graphics card and its OpenGL support, which will look like this.

Renderer: Intel 945GM
Vendor: Intel
Memory: 256 MB
Version: 1.4.0 - Build 8.14.10.1930
Shading language version: N/A

Mac

On 64-bit macOS 10.6 or higher, download and install OpenGL Extensions Viewer from the Mac App Store. Open the viewer and click on the Report tab in the tab bar.

Crash on program start

LibreOffice comes with OpenGL rendering enabled by default and this configuration might cause problems with certain combinations of graphics hardware and their drivers, which can lead to crashes. If LibreOffice crashes immediately on startup, it will not be possible to open the Options dialog and disable OpenGL there, so you have two options:

LibreOffice 5.3 and newer:
- Start LibreOffice in Safe Mode (open "LibreOffice (Safe Mode)" in the Windows start menu or run libreoffice --safe-mode in the Linux terminal).
- Select "Configure" -> "Disable Hardware Acceleration (OpenGL, OpenCL)"
- Click "Apply Changes and Restart"
LibreOffice 5.2 and older:
- On Windows:
  - Download this registry fragment and import it in the registry editor, which will disable the UseOpenGL parameter on Windows.
- On Linux:
  - Open the registrymodifications.xcu file found in LibreOffice's user profile folder and change UseOpenGL and ForceOpenGL entries to false:
  - ```
  <item oor:path="/org.openoffice.Office.Common/VCL"><prop oor:name="UseOpenGL" oor:op="fuse"><value>true</value></prop></item>
  <item oor:path="/org.openoffice.Office.Common/VCL"><prop oor:name="ForceOpenGL" oor:op="fuse"><value>false</value></prop></item>
```

OpenGL Transitions

Implemented and enabled in the 4.4 release series.
