if I see correctly, this issue was introduced in v.4.7.0 in commit c5db181 ansi: add support for xterm OSC 11 https://git.savannah.gnu.org/cgit/screen.git/commit/?h=screen-v4&id=c5db181b6e017cfccb8d7842ce140e59294d9f62 note the deletion of ``` if (--typ2 < 0) typ2 = 0; ``` At least I can't reproduce this issue on v.4.6.2.
