Thanks for looking into it.</p>

<p>If someone deletes something that's meant to be ref-counted it's being used wrong. <br />
If there was a real bug in ManagedTextureNode we would have seen it in all the code that already used it; iconitem, framesvgitem, etc...</p>
<p>This is just a bug in plotter. If you do need to reverse the smart pointer logic to have a weak pointer, keep it within there.</p>
<p>Btw, you don't need managedtexturenode unless you're using the texturecache, since Qt 5.4 you can use QSGSimpleTextureNode::setOwnsTexture. It might help?</p></div></div><br /><div><strong>REPOSITORY</strong><div><div>R296 KDeclarative</div></div></div><br /><div><strong>REVISION DETAIL</strong><div><a href="https://phabricator.kde.org/D10250" rel="noreferrer">https://phabricator.kde.org/D10250</a></div></div><br /><div><strong>To: </strong>mart, Plasma, davidedmundson<br /><strong>Cc: </strong>davidedmundson, broulik, ngraham, plasma-devel, Frameworks, michaelh, ZrenBot, progwolff, lesliezhai, ali-mohamed, jensreuterberg, abetts, sebas, apol, mart<br /></div>
