But i had to symlink it to /usr/lib/x86_64-linux-gnu/ to get all working.

Noticed the same today on Debian stable. Installing the package "libxrender1" did the trick without any need of doing some symlinks.
P.S. I have updated the bugreport and set the correct project (LibreOffice Online) for it.
Yes, libxrender1 was set as a dependency indirectly through another package that has become obsolete for online. As a fix it was now added as a direct dependency, and the issue will be fixed with the next update. Thanks for the bug report!
