From f4d6af40a89e65ec63b250bf76d1bd1021777dd8 Mon Sep 17 00:00:00 2001 From: Gabriel Schneider Date: Thu, 1 Oct 2026 03:06:32 -0300 Subject: A detached session's pty is sized in pixels too, at the last frontend's cell size or a nominal 8x16 before one attached forkShell sized a new pty in pixels (ptyWinsize), but the detached server's resize set xpixel and ypixel to 0, and a pane is resized as it is placed, so a program in a detached session with no frontend (yazi) saw a pty with no pixels and drew no images. CSI 14/16/18 t were already answered at the nominal 8x16 cell.
