Hi there!
I’m having a problem with Unity 2019.4.18.f1 under Linux Mint ‘‘Ulyssa’’. Whenever I’m trying to move/drag any of the editor’s windows to dock it somewhere else it goes completely mental. I tried searching for a solution on my own, but had no luck with that. Below are video showing the issue and console logs:

If it matters, I’ve got recommended nvidia drivers version 460 installed.

Another thing I wanted to mention here, my VS Code is not highlighting errors. It’s the only thing I’m missing and can’t get to work in VS. Screen with installed plugins below:

For the highlighting issue, make sure you have mono installed and in your VS Code settings, set “Omnisharp: Use Global Mono” to “always”.

Thank you, Kevin! I was sure I installed mono, silly me. It seems that for some reason I managed not to (I’m a Linux newbie). Anyway, it works flawlessly now, so many thanks again!

When it comes to weird behaviour of the editor, I guess I won some stupid lottery with it?

Don’t worry about. It the mono thing is non-trivial to figure out. I think I learned it myself by reading the forums here :slight_smile:
