From 5289d4ed13e18fa4430aba27af0d525d2f76fc30 Mon Sep 17 00:00:00 2001 From: nicm Date: Sat, 18 Apr 2020 06:10:15 +0000 Subject: When a redraw is deferred because the terminal hasn't finished reading the data from the last one, other panes could update while waiting, so we set the flag to redraw them all when the new redraw actually happened. But this means a lot of redrawing panes unnecessarily if they haven't changed - so instead set a flag to say "at least one pane needs to be redrawed" then look at the invidual pane flags to see which ones need it. --- screen-redraw.c | 13 ++++++++++--- 1 file changed, 10 insertions(+), 3 deletions(-) (limited to 'screen-redraw.c') diff --git a/screen-redraw.c b/screen-redraw.c index c510fb68..c9e70590 100644 --- a/screen-redraw.c +++ b/screen-redraw.c @@ -438,17 +438,24 @@ screen_redraw_screen(struct client *c) tty_sync_start(&c->tty); if (flags & (CLIENT_REDRAWWINDOW|CLIENT_REDRAWBORDERS)) { + log_debug("%s: redrawing borders", c->name); if (ctx.pane_status != PANE_STATUS_OFF) screen_redraw_draw_pane_status(&ctx); screen_redraw_draw_borders(&ctx); } - if (flags & CLIENT_REDRAWWINDOW) + if (flags & CLIENT_REDRAWWINDOW) { + log_debug("%s: redrawing panes", c->name); screen_redraw_draw_panes(&ctx); + } if (ctx.statuslines != 0 && - (flags & (CLIENT_REDRAWSTATUS|CLIENT_REDRAWSTATUSALWAYS))) + (flags & (CLIENT_REDRAWSTATUS|CLIENT_REDRAWSTATUSALWAYS))) { + log_debug("%s: redrawing status", c->name); screen_redraw_draw_status(&ctx); - if (c->overlay_draw != NULL && (flags & CLIENT_REDRAWOVERLAY)) + } + if (c->overlay_draw != NULL && (flags & CLIENT_REDRAWOVERLAY)) { + log_debug("%s: redrawing overlay", c->name); c->overlay_draw(c, &ctx); + } tty_reset(&c->tty); tty_sync_end(&c->tty); -- cgit v1.2.3
