That likely is a hang up in the graphics testing.
Go to your LibreOffice user profile, %APPDATA%/LibreOffice/4 normally on Windows, and find the file “registrymodifications.xcu”
Open it in notepad, or an XML editor (not Word, Wordpad etc.)
If not already present, add these two stanzas somewhere near the top but below the <oor:items stanza:
<item oor:path="/org.openoffice.Office.Common/VCL"><prop oor:name="ForceSkiaRaster" oor:op="fuse"><value>true</value></prop></item>
<item oor:path="/org.openoffice.Office.Common/VCL"><prop oor:name="UseSkia" oor:op="fuse"><value>true</value></prop></item>
That will toggle your graphics to use Skia in software mode for raster framing instead of Vulkan hardware acceleration.
Alternatively you set both values “UseSkia” and “ForceSkiaRaster” to false. Doing that turns off use of the Skia lib based graphics, and it will enable legacy Windows GDI+ graphics. Maybe not as performant, but of use with graphics processors that have marginal Skia lib support.
If that gets you working, you might check if there are driver updates for your graphics processor. Update and then retest the “UseSkia” true with “ForceSkiaRaster” false–that config would use the hardware accelerated ‘Vulkan’ rendering, know as ‘Metal’ on macOS.
The testing for Vulkan rendering has caused similar issues for folks for some time. Think Mike K is looking at it. For now give that registry edit a try…
