Subject: gnuplot -persist with x11 driver slowly eats up CPU

Date: Sun, 30 Sep 2007 14:35:33 +0200

Package: gnuplot
Version: 4.2.0-4
Severity: normal

running for example gnuplot -persist <<< "plot x**2" allow you to span a
new window that persist when gnuplot exists. but when gnuplot exits leaving
a window, it slowly eats up CPU (6% to 9%, sometimes I see things like
15%), even if the window is minimized.
it seems OK with one window, but this cpu utilization grows up
with the number of window, and it gets noticeable when running CPU
intensive tasks.

Spawned 20 windows, and no noticeable lags nor idle CPU utilization.

Debian version of KDE 3 at the time. Now i'm running 
Enlightenment DR17 from unstable.

Thanks for the info,

gnuplot was recently moved under debian-science control and found a new
{co-}maintainer. I am currently trying to help there by triaging old
gnuplot bug reports,

Since this bug seems to be no longer present, I am closing it. Please reopen
if needed.

Regards,
