Doubling of menubar after installing LanguageTool in LibreOffice

Hi, I’m running LibreOffice 6.3.2.2 on a LinuxMachine (LinuxMint 19.2). After installing LanguageTool 4.7, I noticed some weird behaviour of the menubar. It’s getting doubled after entering a formula in a text-document.

I filed a bug for that in the LibreOffice Bugzilla : 128491 – Doubling of menubar after inserting formula in writer (only if LanguageTool is in use)

I can reproduce the effect always. Disable LanguageTool => Effect is gone, Enable LanguageTool => Double menubar.

JRE = java11-openjdk

Ah, I missed this when I posted here on the same issue. If I open files through caja, I don’t get the problem.

Same problem here, can also confirm it

System: Pop OS 19.10 (Linux) with LO 4.6.1.2

There is a LibO issue about double menu pane tracked at 126870 – Duplicate menu entries for specific user interfaces, GTK3 VCL or GTK3 on KDE with "Global Menu" . AFAIK, that bug is not related to LT extension. Showing up there might (or might not) help fixing that bug. From a distance, UI (bugs) seem not to have priority for LibO devs :-/
