[Touch-packages] [Bug 1510201] Re: AdaptativeLayout take longer to show a page
I mark this as invalid as it is not the AdaptivePageLayout which makes the page to load slower but the content of the page, in particular the QtQuick Repeater component which slows the page loading. ** Changed in: ubuntu-ui-toolkit (Ubuntu) Status: New => Invalid ** Changed in: canonical-devices-system-image Status: Confirmed => Invalid -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1510201 Title: AdaptativeLayout take longer to show a page Status in Canonical System Image: Invalid Status in ubuntu-ui-toolkit package in Ubuntu: Invalid Bug description: Device: krillin Image: Ubuntu 15.04 (r153) I created a small/simple example with Pages using the new AdaptativeLayout.

Alternatively we can add an extra parameter to force page addition to be synchronous. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1510201 Title: AdaptativeLayout take longer to show a page Status in Canonical System Image: Confirmed Status in ubuntu-ui-toolkit package in Ubuntu: New Bug description: Device: krillin Image: Ubuntu 15.04 (r153) I created a small/simple example with Pages using the new AdaptativeLayout.

[Touch-packages] [Bug 1510201] Re: AdaptativeLayout take longer to show a page
We profiled this with Florian, and it ends up that Repeater is no longer creating the bunch of components and then renders, but it creates each delegate asynchronously after which it renders each of them separately. So instead of a 1000 block create then render we have 1000 create + render, and sniffed rendering between creates slows down the things. This will always happen when page is loaded asynchronously and the loaded page has a Repeater, until upstream does something with the Repeater to load faster. Using ListView with a cache to fit the whole model content behaves differently, at least the visible items are created in a block synchronously then rendered, and the rest of the invisible ones are created asynchronously afterwards. So this may be a better approach for use cases we have in the attached example. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-ui-toolkit in Ubuntu. https://bugs.launchpad.net/bugs/1510201 Title: AdaptativeLayout take longer to show a page Status in Canonical System Image: Confirmed Status in ubuntu-ui-toolkit package in Ubuntu: New Bug description: Device: krillin Image: Ubuntu 15.04 (r153) I created a small/simple example with Pages using the new AdaptativeLayout.
