[Bug 1583164] Re: Panel Indicator uses 25% cpu

[Akom]

Still happens on a clean XFCE install on Ubuntu 18.04, exactly like in
#10 (only Ambiance/Radiance themese cause high CPU usage)

[Bug 1583164] Re: Panel Indicator uses 25% cpu

[cipricus]

I have this problem in Mint 19.1 with xfce4-panel 4.12.2 (Xfce 4.12),
based on Ubuntu 18.04. The CPU high load started when switching themes.
Changing theme back solved it.

I cannot reproduce this bug in Xubuntu 18.04.

Can anyone else confirm that this is fixed in the newest release?

[Bug 1583164] Re: Panel Indicator uses 25% cpu

[Akom]

Changing themes fixed this for me on Ubuntu 17.04, as per #3 above
(Settings->Appearance->Styles).

Radiance/Ambiance themes: high cpu usage.
All others: no problem.

Other suggestions did not work for me:
I don't have a ~/.config/gtk-3.0/*.css that was mentioned in #9.
I am already using a Notification Area, as mentioned in #7.

[Bug 1583164] Re: Panel Indicator uses 25% cpu

[hungrywolf]

I was able to solve this by removing/renaming the file ~/.config/gtk-3.0/gtk.css
The file appears to contain several customized gradients that are applied to 
panel applets, on top of whatever theme is already in use.

1. Rename or remove ~/.config/gtk-3.0/gtk.css
2. Kill the process panel-(number)-indica
3. If prompted, click 'Execute' to restart the plugin

After doing this, process panel-14-indica went from 5% cpu to 0%, and
stayed at 0%.

Replacing the gtk.css file, and killing and restarting the indicator
plugin, reversed the process and raised the cpu usage again. For me,
changing which GTK theme I was using had no effect. I am using Xubuntu
16.04.

I can confirm comment #7 that using Notification Area instead of
Indicator Plugin fixes the issue.

[Bug 1583164] Re: Panel Indicator uses 25% cpu

[lz1]

I found the solution (workaround).
The simplest way to avoid this is not to use indicators panel at all.
I added 'System tray' to xfce panel and now everything works fine.
I have Bluebird theme and nm-applet icon at usual place.
There is no hi cpu usage.
Background of system tray corresponds to system theme.

[Bug 1583164] Re: Panel Indicator uses 25% cpu

[cha0s]

I can confirm it is the same for me. I attached a theme to this post. I
place this theme in ~/.themes

If I remove the gtk-3.0 directory from the Xfce-darkness directory and
restart, the CPU usage goes back to normal. If I put the gtk-3.0
directory back in the Xfce-darkness directory, panel-6-indicat AND Xorg
takes up 25%+ of cpu! This is not a weak machine either.

It seems fairly obvious there is some issues with gtk-3.0 themes. Also I
am on xubuntu 16.04

[Bug 1583164] Re: Panel Indicator uses 25% cpu

[Stephan Mueller]

Hi, I've the same problem, but only if I use a GTK3 based theme! If I
use a GTK2 based theme the indicator goes down from around 30% to a load
of around 3%.

So I assume it has something to do with the use of GTK3.

I hope this helps solving the indicator bug :)

[Jakub Vaněk]

It's the same here on Xubuntu 16.04. I managed to lower the CPU usage by
killing indicator-application-service in a loop:

for((;;)) do killall indicator-application-service; done

After a few seconds press Ctrl+C.
