--- Comment #1 from Kai Uwe Broulik <k...@privat.broulik.de> --- I had a quick look with hotspot and it seems like there’s a leak in QRhi somewhere. Seems every window gets its own RHI instance with its own glyph cache which is then leaked. Alas, I haven’t managed to figure out where it comes from or what the remedy would be, or if that’s even the case, or why it only really shows with notifications (I doubt it’s only notifications but they create a new window every time). for reference the leak stack in heaptrack: 2,7MB (33.2%) contribution to peak consumption in QRhi::nextResourceUpdateBatch() in libQt6Gui.so.6 and below. 2,7MB (33.2%) contribution to peak consumption in QSGDefaultRenderContext::glyphCacheResourceUpdates() in libQt6Quick.so.6 and below. 2,7MB (33.2%) contribution to peak consumption in QSGRhiTextureGlyphCache::createEmptyTexture(QRhiTexture::Format) in libQt6Quick.so.6 and below. 2,7MB (33.2%) contribution to peak consumption in QSGRhiTextureGlyphCache::endFillTexture() in libQt6Quick.so.6 and below. 2,8MB (34.5%) contribution to peak consumption in QTextureGlyphCache::fillInPendingGlyphs() in libQt6Gui.so.6 and below. 2,8MB (34.9%) contribution to peak consumption in QSGTextMaskMaterial::populate(QPointF const&, QList<unsigned int> const&, QList<QPointF> const&, QSGGeometry*, QRectF*, QPointF*, QMargins const&) in libQt6Quick.so.6 and below. 2,8MB (35%) contribution to peak consumption in QSGDefaultGlyphNode::update() in libQt6Quick.so.6 and below. 2,8MB (35.1%) contribution to peak consumption in QSGInternalTextNode::addGlyphs(QPointF const&, QGlyphRun const&, QColor const&, QQuickText::TextStyle, QColor const&, QSGNode*) in libQt6Quick.so.6 and below. 2,8MB (35.1%) contribution to peak consumption in QQuickTextNodeEngine::addToSceneGraph(QSGInternalTextNode*, QQuickText::TextStyle, QColor const&) in libQt6Quick.so.6 and below. 2,8MB (35.1%) contribution to peak consumption in QSGInternalTextNode::doAddTextLayout(QPointF, QTextLayout*, int, int, int, int) in libQt6Quick.so.6 and below. 2,8MB (35.1%) contribution to peak consumption in QSGTextNode::addTextLayout(QPointF, QTextLayout*, int, int, int, int) in libQt6Quick.so.6 and below. 2,9MB (35.6%) contribution to peak consumption in QQuickText::updatePaintNode(QSGNode*, QQuickItem::UpdatePaintNodeData*) in libQt6Quick.so.6 and below. 3,0MB (37.5%) contribution to peak consumption in QQuickWindowPrivate::updateDirtyNode(QQuickItem*) in libQt6Quick.so.6 and below. 3,0MB (37.6%) contribution to peak consumption in QQuickWindowPrivate::updateDirtyNodes() in libQt6Quick.so.6 and below. 3,1MB (38%) contribution to peak consumption in QQuickWindowPrivate::syncSceneGraph() in libQt6Quick.so.6 and below. 3,1MB (38%) contribution to peak consumption in QSGRenderThread::sync(bool) in libQt6Quick.so.6 and below. 5,6MB (69.6%) contribution to peak consumption in QSGRenderThread::syncAndRender() in libQt6Quick.so.6 and below. 7,1MB (88.2%) contribution to peak consumption in QSGRenderThread::run() in libQt6Quick.so.6 and below. 7,1MB (88.2%) contribution to peak consumption in terminate_on_exception<QThreadPrivate::start(void*)::<lambda()> >::operator() in libQt6Core.so.6 and below. -- You are receiving this mail because: You are watching all bug changes.
