    Hi,


    We recently updated the kendo version in use by our app to v2016.1.226


    Since the launch of our last version we have an increasing number of users who complain that when they first try to scroll the app, the result is an empty screen as can be seen in the attached image "empty-screen-galaxy-s4.png"

    We know that all those users have Android 5.x (e.g. 5.1.1, 5.0.1) and various devices (Galaxy S4, Oneplus X, Huawei Mate s).
    Our app is using kendo listview and we tried to debug this issue with a device connected to Chrome Dev tools. We reached the following conclusions:
    - Trying to reset kendo scroller has no effect on the problem
    - Even though it may look like the content is scrolled up outside of the screen area, the debug shows that the view and the listview are correctly placed on the screen, as can be seen in the attached image listview-correctly-placed.png

    Are you familiar with any other cases of this nature? Any idea how can we solve them?

    Thanks,

    Ron.

    Hi,

    To me, this seems like one of the cordova (I assume you use it) 3d transform/texture obscurities, usually resolved by setting a bunch of strange android related configuration options or by using Crosswalk. We are not experts in this matter. I may suggest that you contact the Platform AppBuilder support channel, as they know more about this subject.

    We tried using Crosswalk but it did not help. So we'll try to contact the Platform AppBuilder support channel as you suggested.

    BTW - We are no longer able to see the thread in the AppBuilder forum - so can not see any answers that might appear there.

    Hi Ron,

    The other thread is now not accessible via the public site and it looks like an issue on our side. I have forwarded it to the responsible developers for investigation. Please excuse us for the inconvenience.
