Bug#1001626: enlightenment: Starting gkrellm or qmmp, enlightenment process takes too much cpu cycles

[Adrian Immanuel Kiess]

Dear Ross,

I can sharpen this in the way that I use the gkrellm instances remotely
over SSH connections. Also, other GTK+/GNOME3 applications executed
remotely over SSH and displayed locally on my Enlightenment XOrg window
manager session take a lot of high CPU% cycles.

Maybe this helps identify the bottle-neck.

Sometimes it takes a low CPU% percentage at start right after booting
into Englightenment, but having eight gkrellm instances (seven remotely
via SSH) make take Enlightenment one full CPU core after having it
run for a while. 

This does not happen when I don't run gkrellm. Enlightenment takes as
low as 0,7-6% CPU% usage, even after having running Enlightenment for
two days. Spurring on gkrellm, the same affect happens again.

Changing the refresh time/rate of gkrellm in the gkrellm preferences
does not change the effect.

I hope this can be fixed! If no solution can be found (maybe it has to
do with some library, I don't know) I will contact 
https://www.enlightenment.org/contact.

With best wishes.

Sincerely,

Adrian Kieß
