Qt 4.8 GraphicsView slower than 4.8 RC
Greetings Qt devs,
I’ve Just tested the QGraphicsView on Win32 Vista in software.
There is an important performance hit between 4.8 RC and 4.8.
Animations and transitions seem slower. You can notice that in qtDemo 4.8 and 4.8 RC.
Has the software renderer been tweaked between 4.8 RC and 4.8 ?
Please submit a bugreport via "Jira":http://bugreports.qt.nokia.com
it's fixed ! big thanks to Jonathan Liu
strange that nobody from Qt try to fix this before : it was just making Windows QMl application unusable under Windows !
Agree, that was quite a big regession on Windows.
And it's a one letter fix :D.
Glad it got fixed this way!
I need to force image to asynchronous:true to the same smooth animation as in Qt 4.7.4 (for example coverflow with HD image)
Will this fix (performance drop seems rather significant) be included in the official SDK or available through the SDK maintenance app? Or is it only available through Git and in future releases of the SDK?
