I use LXTerminal 0.20. with XFCE 4.12.2 on Linux Mint 18.2 (upgraded from 18.1).
When I copy text in some desktop app and paste it into an LXTerminal session, I get
1~ prepended and appended, respectively, to the text. So,
This doesn't happen with XFCE4's "native" terminal app (
xfce4-terminal), so not the same issue as in this question - and not resolved by the answer there. It also doesn't happen if I copy the text to apps with GUI (i.e. the text itself, in the clipboard, is fine).
Why is this happening and what can I do to avoid it?
