--- Comment #10 from Vlad Zahorodnii <vlad.zahorod...@kde.org> --- It looks like kwin or rather breeze decoration spends a lot of cpu cycles in fontconfig stuff, I wonder why. Could you try running kwin_x11 with QT_LOGGING_RULES="*.debug=true" envvar and post its output here, maybe Qt would print something QT_LOGGING_RULES="*.debug=true" kwin_x11 --replace This also explains why the issue is present when compositing is disabled. Breeze decoration would be still used in that case. -- You are receiving this mail because: You are watching all bug changes.
