High CPU usage on xfce4-panel in XFCE v4.18 #61

Closed melroy89 closed 1 year ago

melroy89 commented 1 year ago

Since I upgraded to XFCE 4.18 I noticed high CPU usage of the xfce4-panel process.

The root-cause was in Panel->Panel Preferences -> Appearance tab-> Background style-> "None (use system style)".

The moment I changed this to "Solid color" instead, the high CPU usage issue went away..

I think you need to look into the default panel style, especially the background..

Thanks in advance...

Hi, I'm so sorry for the very late response, Could you please tell me how can I see such behaviour? I've testing my themes and I've never faced that issue, I would be amazing if you could help me.

So I use Juno-v40 with Linux Mint 20 (XFCE).

Then I go to the Panel Preferences and select "none" as background style:

And this is causing the xfce4-panel use about 20% CPU (constant usage!):

Thank you so much for your help, Could you please make me a big favor and check if replacing the file Juno/gtk-3.0/gtk.css with this one(extracted) fixes the issue, please?

I need to switch between another theme and your GTK theme(at Appearance in XFCE) to be sure the new gtk.css file gets loaded. But yes, it seems to be fixed! 🥳

It's now around 0.7% CPU load, sometimes 0.0%.

When switching back to the old version (and switching themes to another theme and back to Juno v40) it seems to be returning. Meaning that I can reproduce the problem on the old version and your new css file the issue seems to be fully resolved.

One side note: I did copied to: Juno-v40/gtk-3.0/ (so not Juno), because I'm using v40. But I copied your file to the v40 version. I hope that doesn't matter too much. Ideally you may want to patch all your versions 👍🏽 .

It should be patched already right? Or do you still need the workaround?

Actually no it's all good. As soon as I switched to stock background my laptop calmed down. I just installed xfce and was busy configuring and noticed the cpu graph on the panel I JUST put there earlier was going haywire. I'm sure I wouldn't have noticed it for a while. There's a ton of processes in the task manager but only like 4 were running
