Sorry, I don't understand fully, could you clarify what do you mean by "but I failed, The lag still existed."? Does it mean you failed to reproduce issue in the new user? In which user lag still existed? Did you change KWin/Plasma renderer? You can check by running: kcmshell6 kcm_qtquicksettings If you were not able to reproduce using new user then that's kind of a good news - you can fix your old user by changing configuration (but which one?) or wiping it out entirely. If you were able to reproduce, that's kind of a good news as well: if you have time and will it should be possible to pinpoint abusive config. This might be tedious, because each manual config change (when you are replacing files) should be done when new user is not logged is not running, because KWin/Plasma/whatever can flush it's current config on shutdown. -- You are receiving this mail because: You are watching all bug changes.
