--- Comment #16 from Thomas Lübking <thomas.luebk...@gmail.com> --- QML users in KWin are - all window decorations except breeze (and likely oxygen, which you've been using) - most tabboxes (except for cover- and flipswitch) - this would be the major candidate? - the desktop switching OSD On profiling, there's http://doc.qt.io/qtcreator/creator-qml-performance-monitor.html but I'm neither sure whether it actually does runtime profiling and cache analysis seems restricted to the commercial version. Classical profilers (callgrind) didn't turn out to be any helpful regarding QML on my only attempt (you'll figure that it spends most of the time in resolving metaobject data from a slot invocation) -- You are receiving this mail because: You are watching all bug changes.
