Ah, thanks for pointing that to me. I had guessed we had to do some work to detect the terminal capability and conditionally output escapes or not, but I'm glad that's not how it works :-). > My recollection is that there was a bug in libvte back then: > > https://issues.guix.gnu.org/38940#6-lineno18 > > That bug mentions a much older VTE though, so I wonder if it’s a newer > regression? According to [0]: > At this moment, terminals known to be buggy (OSC 8 resulting in > display corruption) are VTE versions up to 0.46.2 and 0.48.1, Windows > Terminal up to 0.9, Emacs's built-in terminal, and screen with 700+ > character long URLs.
