Please accept my apologies. The issues I saw had to do with broken 3D acceleration in the VMs I used to test this. I can confirm this is in fact working in the 6.3.3 deb from:
https://www.libreoffice.org/download/download/?type=deb-x86_64
This issue is still present downstream in Ubuntu however, but that's my problem not yours.
