Subject: knotty: Reduce refresh of footer
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=5d706c7cd6ee8d83b67ff18312d4c8119bea8878;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

knotty: Reduce refresh of footer

When displaying larger number of events the client can get caught up in displaying
the footer, then immediately overwriting it. To avoid this, wait for pauses
in the event stream before displaying the footer to give a slightly more
friendly feel to the UI.
