About as sure as I can be without having actually verified with `ps`. Opening a new window through the menu gives a similarly afflicted window, and all already open tabs lost their keyboard input yesterday. IIRC the symptom was more tab-specific with Konsole4 (ie only a single tab at a time would be affected and I could use "New Tab" or "Clone Tab" to escape from the issue.

I've also tried to toggle the keyboard layout to and from a different language. That particular action tends to help me when KDE apps drop the "dead" aspect from the dead key I use to get accented letters ("Macintosh" keyboard layout, Alt-Gr serves as a deadkey such that AltGr+e,e gives an é). That particular symptom may be KDE PIM trying to switch my keyboard when it detects a language setting in an email, I realise now.

I cannot say as I have yet to figure out how to trigger the issue.

Other than clear the screen, nothing.

It's possible, though it's surprising that I'm only discovering that now. I've been using tcsh since the 90s, and Konsole for years too...

Thanks for brainstorming with me anyway.
