Vitalium has been updated, several bugfixes and some LV2 presets now included by default. (note: lv2 presets, not vitalium/plugin-side presets)
If you do not have a way to install or build from source, grab the deb files from https://kx.studio/Repositories:Plugins
Please let me know if you find any more issues. Hopefully we are close to having it stable, so an official release is made.
