Note: there is a fix for this bug but, unfortunately, the fix will not be available until the LibreOffice 7.6.5 release.

However, if you want to test the fix now, the fix is already in LibreOffice 24.2.0 Beta1. Download links for the beta version are below:

Mac Intel:
https://www.libreoffice.org/download/download-libreoffice/?type=mac-x86_64&version=24.2.0&lang=en-US

Mac Silicon:
https://www.libreoffice.org/download/download-libreoffice/?type=mac-aarch64&version=24.2.0&lang=en-US

Note: beta versions of LibreOffice are installed in /Applications/LibreOfficeDev.app so it will not overwrite your existing LibreOffice 7.5.x or 7.6.x installation. But, you may need to double-click on /Applications/LibreOfficeDev.app in the Finder to be sure that you have launched the beta version.

Please reopen if the beta version does not fix this bug.

Update: a tester has found a workaround without having to install any beta versions: switch to Skia/Metal rendering.

To enable Skia/Metal rendering, do the following steps:

1. Open the Options dialog by selecting the LibreOffice > Preferences menu
2. Select LibreOffice > View in the left panel
3. In the right panel, check the "Use Skia for all rendering" and uncheck "Force Skia software rendering" checkboxes as shown in the following screen snapshot:

4. Press the "OK" button and restart if prompted
