@Nils-Petter-Skalerud i'm aware of this ! that's why i needed to know if there's a known fix or an export maybe that resolve this without touching the qt code or at least my qml code to make it work. I'll be waiting for your respond ! i hope you'll not forget to ask the expert, this can really help me :') thank you !!

@SGaist I tried to update my Qt to 6.8.3, but I encoutered some issues about files not found. You can see in this topic : https://forum.qt.io/topic/162706/issue-encountered-with-c-compilation-in-qt-creator-and-msvc?_=1752664613398

Very embarassing but I found out I have to to build in RELEASE mode to have the full GPU acceleration. In practice that means doing cmake -DCMAKE_BUILD_TYPE=Release .. Then run windeployqt again. There should be QWebEngineProcess.exe - if there is QWebEngineProcessd.exe (the d for "debug") that means it is still in debug mode and will be slow.

It uses the raster engine. See here for historical informations.

Hi @atessadri, I would like to know how to understand when the animation embedded in the transition is really finished. Is there any signal to catch ? Yes there is. Transition has running property so you can use the onRunningChanged signal handler inside it. Eg: Transition { ... onRunningChanged: if(!running) console.log("Stopped") } Sorry I don't have answers to your other questions.
