[Solved] gvim-7.4.2143-1-x86_64 Has Lag When Navigating Up/Down

On upgrading gvim to gvim-7.4.2143-1-x86_64, I experienced intermittent lag when navigating up/down (i.e. k/j keys).  The lag itself would last for about a second, and I could not predict when it would happen, but frequency was about once every ten seconds during a typical session.

I did not experience any lag when using vim instead of gvim, nor when I ran a vanilla gvim session with "gvim -u NONE".

I have fixed the issue temporarily by downgrading to gvim-7.4.1910-1-x86_64 and vim-runtime-7.4.1910-1-x86_64, but I'm not sure what the source of the problem is.  I have a decently-sized vimrc, but until I encountered this problem, both vim and gvim have always run at light speed on my system.  I run vim within (and launch gvim from) urxvt, and I'm using i3wm.  Is anybody else experiencing issues?

Re: [Solved] gvim-7.4.2143-1-x86_64 Has Lag When Navigating Up/Down

I've isolated the problem.  The lag depends on a single line in my vimrc.  When I remove this line, gvim no longer does its intermittent one-second hangups:

 set showcmd 

Problem...solved?  Should I contact upstream vim/gvim devs?  This lag I'm experiencing can't be happening to too many other people, i wouldn't think, because lots of people must use showcmd in their vimrc.  But it is an issue.

Yes. Of course, check if there's an existing bug report first.

I'd say it's solved when it's solved upstream. wink Feel free to link the report btw, in case others want to follow progress.
