Unable to create walls, rooms, etc. Plan is unlocked
I have tried uninstalling and reinstalling, updating, everything I can think of. It looks like it glitches out when I start to create a wall, it shows a sliver of the wall for like 1 second while I'm dragging it and then it's gone.

Try posting the information from the About dialog so we can see the versions. Linux can get screwy when over-zealous package managers dump the included java runtime. SH3D likes its bundled 1.8.0, which of course is now absolutely ancient. Avoid package manager versions of SH3D. Get the old, last, open source version 7.5 release from sourceforge.
If the idea of such an old JRE bothers you, a guy posted a repro on github (search DobryDom3D) which is a fork of the GPL version which was made compatible with the latest-ish Java 26.0 with some other performance tweaks. He's since gone a bit quiet, but I think he had a bit of a busy personal life period coming up, so I don't bug him. I posted a couple of PR's there. Strangely nobody else seems to be looking into it. <shrug> We're not going to be getting anything new and open source from Space Mushrooms from what I can tell.
The other thing is graphics drivers. I remember there was a period (quite a while ago) where certain versions of AMD drivers caused all manner of wild glitches. There were some long threads in the forums about that if you have a search around.
