Description Roderick Johnstone 2015-07-16 15:55:49 UTC

When using konsole, the output is often delayed for up to a few seconds.

This is seen both when running a chatty app like a continuous ping or when typing commands into the shell.

Type ahead is recorded correctly and eventually echos correctly.

In the ping test, after a period of no output, all the pings are echoed to the screen with normal ping times, ie there is no network hangup.

A similar ping test run from xterm shows no output hangup.

While the ping output  is hung up typing into kate is still echoes to the screen.

Reproducible: Sometimes

Steps to Reproduce:
1. Start a KDE session
2. Open konsole and run continuous ping to nearby host
3. 

Actual Results:  
Every few minutes the ping output stops for up to a few seconds and is then displayed normally with normal ping times.

Expected Results:  
Output from ping is echoed regularly with every ping.

The screen output hangups are very noticable in everyday work just typing into the shell in konsole.

I do have some strace output from a konsole running a regular ping test, covering the period before during and after one of these hangups.

This seems to have been fixed by some system update in Fedora 22.
