I first noticed this in 17.04.2 but it is also present in 16.12.0. It may b= e a regression in QtWebEngine 5.8.0 but I do NOT observe the same glitch in Qupzilla using the same Qt install. The issue also disappears when switchin= g to the KHtml engine. The issue also disappears when I use the XCB QPA (still on Mac). Any chance it could be related to these terminal warnings? ``` QWidget::paintEngine: Should no longer be called QPainter::begin: Paint device returned engine =3D=3D 0, type: 1 QPainter::translate: Painter not active QPainter::setClipRect: Painter not active QPainter::save: Painter not active QPainter::setRenderHint: Painter must be active to set rendering hints QPainter::fillPath: Painter not active QPainter::restore: Unbalanced save/restore QPainter::hasClipping: Painter not active QPainter::setPen: Painter not active QPainter::setBrush: Painter not active QPainter::drawRects: Painter not active QPainter::save: Painter not active QPainter::setRenderHint: Painter must be active to set rendering hints (etc) ``` --=20 You are receiving this mail because: You are the assignee for the bug.=
