[SOLVED]Issue with particle system and hanging window
-
With the downloaded Qt5.0.2 - msvc2012_64 on win7 when I try to move the window of the following qmlscene, the window keeps hanging at its current position and doesn't react anymore until changing the focus with alt+tab.
@
import QtQuick 2.0
import QtQuick.Particles 2.0Rectangle {
width: 224
height: 288
color: "black"
id: backgroundParticleSystem { anchors.fill: parent ImageParticle { source: "star.png" colorVariation: 1.0 } Emitter { width: background.width; height: 1 size: 8 sizeVariation: 5 anchors.top: parent.top lifeSpan: 6000 velocity: AngleDirection { angle: 90 angleVariation: 1 magnitude: 150 magnitudeVariation: 100 } } }
}
@Without the particle system I can move the window around. I already recognized this behavior in 5.0 but I thought this would be fixed in an upcoming version.

There is a rather ugly issue with timers starving system events when you combine msvc 2012 with win7. In Qt 5.1 there is a new renderloop for Qt Quick for windows which, amongst other things, avoids this particular issue.

Thanks for your reply, so I'm looking forward to Qt 5.1.
