rxvt-unicode sluggish after recent update

Ashren · 2017-02-08 09:31:21

After upgrading yesterday to the latest packages I notice that rendering with rxvt-unicode has become laggy. Using intel with the uxa.

No errors in Xorg.0.log

Anyone here have similar issues?

Xterm seems not to have this issue.

What packages did you update?

Are you using rxvt-unicode from the official repositories, or from the AUR (like me)?

If you remove your "~/.Xresources" and "~/.Xdefaults" files and restart X, is the issue still present?

I found out that is was the following in my .bashrc which was the cause:

# After each command, save and reload history
export PROMPT_COMMAND="history -a; history -c; history -r; $PROMPT_COMMAND"

So, upgrading to bash 4.4.011-2 somehow causes the following with urxvt (both the official and the one from aur) and the .Xresources above:

-bash: PROMPT_COMMAND: line 0: syntax error near unexpected token `;'
-bash: PROMPT_COMMAND: line 0: `history -a; history -c; history -r; history -a; history -c; history -r; ; printf "\033]0;%s@%s:%s\007" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/\~}"

Before I figured this out I switched to st, which is working just as fine as urxvt. I'll stick with st for a while now I think.

Aaaah!

Deleting the marked semicolon from /etc/bash.bashrc also fixes the problem.

case ${TERM} in
  xterm*|rxvt*|Eterm|aterm|kterm|gnome*)
    PROMPT_COMMAND=${PROMPT_COMMAND:+$PROMPT_COMMAND this one --> ; }'printf "\033]0;%s@%s:%s\007" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/\~}"'

This means I also had the problem with xterm. My .Xresources masked the stderr output for some reason.

Why this problem suddenly occurs I have no idea yet. On my desktop machine I'm using bash 4.4.011-2, urxvt with the same .bashrc and there is no issue.

The plot thickens.

This problem only occurs in XMonad.

No idea why this causes sluggishness in rxvt (except that you should be likely using urxvt), but you're too smart for bash:
Do

export PROMPT_COMMAND="history -a; history -c; history -r"

and see what happens ;-)

Thanks, seth.

rxvt-unicode is urxvt.

It appears problem was with the export part (but only when using XMonad for some reason).

Apparently there is no reason to export PROMPT_COMMAND since it is an environment variable for bash.

Frankly, I can't see the point of appending the $PROMPT_COMMAND variable to PROMPT_COMMAND and I can't remember why it made sense. I was probably following some guide.

Anyways, after yesterdays update it stopped working with export, and only when using XMonad, which is rather strange.

I have decided to stop wasting time on troubleshooting this minor issue.

This is what I ended up with in .bashrc

PROMPT_COMMAND="history -a; history -n"

Thanks for your time.
