--- Comment #9 from Lukáš Turek <8...@8an.cz> --- Actually, the window size is correct, only the placement of buttons is wrong (window title is positioned correctly). So the problem is somewhere in Decoration::updateButtonsGeometry(). It seems that captionHeight() sometimes returns a wrong value. This patch is a quick workaround, but the real cause is likely somewhere outside Oxygen decoration. Breeze is not affected, because it doesn't use captionHeight() to calculate the position of buttons. --- a/kdecoration/oxygendecoration.cpp +++ b/kdecoration/oxygendecoration.cpp @@ -350,9 +350,9 @@ void Decoration::updateButtonsGeometry() auto s = settings(); // adjust button position - const int bHeight = captionHeight() + (isMaximized() ? s->smallSpacing() * Metrics::TitleBar_TopMargin : 0); + const int bHeight = buttonHeight() + (isMaximized() ? s->smallSpacing() * Metrics::TitleBar_TopMargin : 0); const int bWidth = buttonHeight(); - const int verticalOffset = (isMaximized() ? s->smallSpacing() * Metrics::TitleBar_TopMargin : 0) + (captionHeight() - buttonHeight()) / 2; + const int verticalOffset = (isMaximized() ? s->smallSpacing() * Metrics::TitleBar_TopMargin : 0); const QVector<KDecoration3::DecorationButton *> leftButtons = m_leftButtons->buttons(); const QVector<KDecoration3::DecorationButton *> rightButtons = m_rightButtons->buttons(); -- You are receiving this mail because: You are watching all bug changes.
