has anyone else found high cpu use in zorin 16 pro lite on panel-#-appmenu?
1253 home 20 0 289388 36736 27584 S 34.2 1.0 5:18.54 panel-2-appmenu
this is in one computer, then i tried changing the zorin desktop appearance theme in a second test computer that was similar make and model and that "panel-2" changed to panel-29-appmenu, but still used from 15% to 30% of the cpu.
when i used htop for more details, this is the readout i get on the mac looking zorin theme:
/usr/lib/x86_64-linux-gnu/xfce4/panel/wrapper-2.0 /user/lib/x86_64-linux-gnu/xfce4/panel/plugins/libappmenu-xfce.so 2 16777224 appmenu AppMenu Plugin Display AppMenu (Global Menu)
don't know if this is relevant. when i open the settings manager from the menu it shows the power icon on the docklike panel, but open the settings. if i add that to the dock and close, when i click to open, it opens just the power settings. there is no way for me to simply add the settings manager on the docklike panel (the settings manager icon is pictured, but because i added a launcher from the panel settings, but when clicked, it still launches the power manager). i can write the settings manager into the .rc file for the docklike panel - so i know a work around for this issue, but when i was testing out just running those 2 settings from terminal, this is what i got and don't know if this is contributing to the high cpu.
The gtk warning is normal and unrelated. what you describe sounds more like a memory leak.
My Honest Method for dealing with Memory leakage is to - reinstall the OS.
I know that sounds non-trivial. to me, it is. I back up everything regulraly, use a script for reapplying my PPA's and customizations, accessories and applications- so it is pretty quick and painless.
i've installed the os about 10 times in 3 days. i've tested it on 4 different minisforum models. same thing happens every time. what seems to be the trigger is as soon as i pick a layout from the zorin appearance that's when the panel-#-appmenu starts eating cpu. i've installed, reinstalled and then tranfered a clone on and the problem continues to follow along. it's been fluctuating from about 10% cpu to almost 40% cpu. what i can't figure out is what is making it move within this range. i've tried removing panels and launchers and don't see it change too much. i do a lot of customization, so it's not quick and painless for me even with a lot of scripts to help the process along - as well as a step by step spreadsheet for setup, but i get what you're saying. that's why i make clones and setup that way. if z16lite passes some of my testing, i'll be installing it in about 150 computers. this memory leak seems to be about the only thing that i have to get a handle on to want to make the move from z15 to z16. i have found a few things that were broken on the xfce/ubuntu side, like the icons disappearing in the applications menu and wine needing a tweak to start .exe's instead of wanting to install them every time you try to run them.
i just did a test going through each zorin appearance layout and watching the system on htop. the 2 that i'm most interested in with 2 panels, one on the top and one on the bottom seem to be the the ones that hog cpu. especially the mac looking layout - which is my primary choice because i have guys that are familiar with macs using these machines. i assume that docklike taskbar is one of the big reasons for the cpu usage.
Is that on Core? I am not aware of Zorin OS Lite offering Zorin Appearance > Layouts. I use Zorin OS Lite.
Zorin OS Lite does not offer a Mac Style Layout, as the Window Manager can be easily set to move titlebuttons to the left.
I think these comments warrant tagging @AZorin and @zorink to review the commentary here as these are general Zorin OS operations that need to be addressed.
Every user cannot necessarily tweak Wine, for example. Also to address anything that may have been misunderstood.
so i autoremoved xfce4-appmenu-plugin and vala-panel-appmenu-common because it said they were both installed, then i just reinstalled xfce appmen and got even worse cpu usage. it stayed closer to just under 40% cpu usuage. and got closer to 45% when i opened smplayer which has one of the more dense global menus - and one i have to use often.
next test = i changed from zorin dark color style in the appearance settings to adwaita-dark (one of the pre installed styles) and my cpu usage on the panel-#appmenu in top disappeared. because now it was using less that 1% cpu and moved way down the list. so ultimately this seems to be something with the zorin styles. now that i am using the different style even other things that were using high cpu have gone down. like xorg and even vino, which i've been using to remote in. there is nothing using even 1% now. and when i go back to zorinblue-dark style, xorg jumps up to 15% and the panel-#-appmenu jumps up to 30%.
also discovered this. all the icon styles have a error next to them. i have not installed any extras, this is what came with zorin. and i actually picked the adiwaita dark style for the desktop, but those icons are missing for that.
i did, but i'm just trying to find things that might have been contributing to the zorin style choice cpu leak. i'm not a programmer so i'm just putting it all out there in case someone else might catch something from what i'm posting.
