A command task streams its output into a view from its own goroutine. To track soft-wraps (so cursor-positioning escapes from a pager land on the right line) the write path read the view's live InnerWidth, and the pty setup read its InnerSize -- both off the UI thread, racing the UI thread mutating the view's dimensions during layout. Capture the width on the UI thread instead and hand it to the task: the escape interpreter keeps a screenColMax it reads from, seeded in NewView and refreshed per render via View.SetContentWidth (called from newCmdTask/newPtyTask before the task's goroutine starts), and the pty size is computed in the after-layout callback rather than in the task's start func. The view's dimensions stay UI-thread-only; the task uses the snapshot rather than reading them live. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
