John, can you please confirm if this is still an issue with Konsole 20.08.1+.
Comment 2 John Haxby 2020-10-26 10:35:38 UTC
I haven't had this problem in a while, I'm not sure when it was fixed -- it's certainly not an issue in 20.04.1 (F32) or 20.08.1 (F33).
Comment 3 Justin Zobel 2020-10-26 11:03:13 UTC
Thanks for the update John, I'll mark this as resolved. If the issue occurs again please feel free to open a new bug report.
