--- Comment #60 from Thomas Lübking <thomas.luebk...@gmail.com> --- This is not a bug in KDE (let alone KWin) The bug exists in every Qt 5.5 version. Older Qt versions have randr related sefaults in QtQuick (will affect plasmashell, kwin and everything else that has QML bits) and so does at least Qt 5.6.0 (unstashed by the restorage of the pre 5.5 behavior to prevent these crashes) Ubuntu could likely "backport" this in Qt - while the resolving commit is a bit bigger, the breaking one is just (afaics pretty much unmotivated other than the broken anyway QtQuick part) http://code.qt.io/cgit/qt/qtbase.git/commit/src/plugins/platforms/xcb/qxcbconnection.cpp?id=51ada7734ad780178ecced11e0dff454dfc2e5f2 -- You are receiving this mail because: You are watching all bug changes.
