From 319f43e1660cfee71f8479626c8f48020f9642cc Mon Sep 17 00:00:00 2001 From: Stefan Haller Date: Fri, 17 Jul 2026 14:00:06 +0200 Subject: [PATCH] Schedule a redraw when resuming from suspension Until now the repaint after fg was accidental: it only happened because the suspend keybinding handler still had a flush pending on the UI thread, and only if that flush happened to run after the SIGCONT handler had re-engaged the screen. Now that flushes are skipped while suspended, losing that race would leave the screen blank until the next input event arrives, so schedule a redraw explicitly (#5309). --- pkg/gocui/gui.go | 5 +++++ pkg/gocui/suspend_test.go | 3 --- 2 files changed, 5 insertions(+), 3 deletions(-) diff --git a/pkg/gocui/gui.go b/pkg/gocui/gui.go index 2785f07d4..57818960c 100644 --- a/pkg/gocui/gui.go +++ b/pkg/gocui/gui.go @@ -1976,6 +1976,11 @@ func (g *Gui) Resume() error { g.suspended = false + // Schedule a redraw of the whole screen.
