Just wanted to let you know I now experienced this when I wasn’t even running subspace at all. Pretty much nothing other than that other process, Brave browser and a text editor, heh. So it’s either that other process, Brave, or some recent kernel bug or something (and I say that last only cause you said it affected you too). But subspace is off the hook.
Didn’t happen to me since, at least not that I noticed. Very odd behavior, whatever the root cause of it is.
