https://bugs.kde.org/show_bug.cgi?id=348401 --- Comment #6 from djx --- I ran all the steps that you have told me. If I use "kcmshell5 kwineffects" And then open Desktop Effects windows it shows up "This configuration section is already opened in KDE Control Module" and doesn't freeze for 30-60 seconds. However if I open "Windows Manager Settings" and then try to run "Desktop Effects" I have the same problem. -- You are receiving this mail because: You are watching all bug changes.
