When using xfce as GUI for ubuntu 22.04 I sometimes get high CPU usage according to htop, sometimes over 60%.I use Ubuntu 22.04LTS and xfce4-panel 4.16.3 (Xfce 4.16)I have searched the internet, but the only solution I found was xfce4-panel --restart which does help, but only temporarily. Is there a structual solution for this ?I thought about a cron job every two hours, but cron cannot access an X display, and is just another bandage rather than a real solution.Do some apps (Thunar, Brave, Firefox, Stellarium) surge the CPU usage ?Update: I found that switching themes is one of the causes.I fixed it by appending xfce4-panel --restart or xfce4-panel -r after the command to switch themes in the launch panel 'dark mode'.
So my switch to light mode is now:
[Desktop Entry]Version=1.0Type=ApplicationName=Light modeExec=sh -c "/usr/bin/xfconf-query -c xsettings -p /Net/ThemeName -s Kimi-v40 && xfce4-panel -r"Icon=goa-panelCategories=SystemX-XFCE-Source=file:///home/user/.local/share/Applications/Light.desktopComment=Path=Terminal=falseStartupNotify=falseMight be a solution, I'll try.
Does anybody recognize this issue ?
