<div dir="ltr">I had a similar problem with urxvt while running xmonad where urxvt would often not render the last line of output until the terminal received some input. It turned out I had compton configured incorrectly. I needed to add the flag --xrender-sync. I don't know if that's your exact problem, but I hope it helps.<br></div><br><div class="gmail_quote"><div dir="ltr">On Tue, Mar 7, 2017 at 6:34 PM Brandon Allbery <<a href="mailto:allbery.b@gmail.com">allbery.b@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr" class="gmail_msg"><div class="gmail_extra gmail_msg"><br class="gmail_msg"><div class="gmail_quote gmail_msg">On Tue, Mar 7, 2017 at 9:17 PM, Richard Watson <span dir="ltr" class="gmail_msg"><<a href="mailto:rwatson@imap.cc" class="gmail_msg" target="_blank">rwatson@imap.cc</a>></span> wrote:<br class="gmail_msg"><blockquote class="gmail_quote gmail_msg" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div id="m_4651701453547901878:1yh" class="m_4651701453547901878a3s m_4651701453547901878aXjCH m_4651701453547901878m15aabb2f0631c2e5 gmail_msg">I notice that when certain GUI application are running (e.g. Chrome, vmplayer, but not firefox & thunderbird) my urxvt terminal renders *really* slowly, redrawing the window line at a time!

Could there be an xmonad issue here? Has anyone else experienced something similar?
