I really wish OP would try a distro other than Manjaro. But since they are, frankly, I am not at all surprised at stability issues. I do not think I have seen any of these issues on a non-Manjaro distro. For some more context:

Manjaro consistently applies incomplete and WIP patches into their builds, causing that sort of instability. Every time I have had a strange issue filed in a program I maintain, it has been traced back to Manjaro doing something like that.
