This is the first I've heard of it, and as a Linux user I feel like it's the kind of thing I'd either know about or experienced first-hand. What kind of system would do that? And "for a long time", like, you can't ever login anywhere, it's kind of obvious and breaking functionality badly, how can this exist for more than a single release if at all?
To be clear, it’s intermittent. Perhaps one in 500 times an input is focused, it exhibits this behavior.
I have experienced this so many times over my life with so many different hardware/software configurations, and I have to assume others have as well. It hasn’t happened in years but could explain why the “fix” described in the parent post was implemented.
