Performance decrease after launching camera and changing the view
I have two pages in a page stack. First is the main view, second contains Camera element. Main view opens view with the Camera. After going back from Camera to the main view there is a significant drop in application performance. The animation and transitions are laggy.
I wonder if I should close the camera somehow and release resources before leaving the page? And how to do it in QML?
And up. This is still unsolved issue.
Tried dynamically loading and destroying Camera component. Still there is a significant decrease in performance after Camera is loaded and destroyed.
Now an interesting observation: this issue doesn't happen with Nokia 701 running Symbian Belle.
But on Nokia E7 with Symbian Anna this is very valid.
Same issue here.
Just before the camera launches, the app comes back to the phone's menu during 1 second.
After that, I can see the phone's menu between each pagestack transitions and the transitions becomes very slow.
Symbian Anna on N8.
I can't speak for this exact case (or why it would differ between Anna and Belle for example) but in general, once you create a component, it will have bindings being re-evaluated if any of the properties those bindings depend on change (eg, due to an animation). Thus, the cost of not destroying an invisible element is non-zero.
