I use qt and quick to develop applications for bb10,I have encountered
how to lock landscape mode in qt/quick project.
I have changed the descriptor file to landscape mode and screen
orientation in main.cpp to lock landscape mode, but still can't
landscape the application
some times when i succeed to run at landscape mode the application
crashes when go back to portrait at running time.
and this shown on the console
Qml debugging is enabled. Only use this in a safe environment!

QBBWindow: invalid buffer count. Expected = 2, got = 1

I've just got the same when taking a plain(ish) Qt app which used to work on BB10. Switching from portrait to landscape by rotating the device:
"QBBWindow: invalid buffer count. Expected = 2, got = 1"
This used to work, but isn't working any longer with the latest NDK (10.0.9, build ID = v201212072306) and Dev Alpha A image (10.0.9.1675)

I get a similar problem with a Qt/C++ app when running my app installed on the Dev Alpha. My bar-descriptor.xml file has the following:
<initialWindow> <aspectRatio>landscape</aspectRatio> <autoOrients>false</autoOrients> <systemChrome>none</systemChrome> <transparent>false</transparent> </initialWindow>

yalnte, even with
<initialWindow> <autoOrients>true</autoOrients> <systemChrome>none</systemChrome> <transparent>false</transparent> </initialWindow>

It runs fine when executed via the IDE or when holding the Dev Alpha in landscape.
If I open my app when holding it in portrait it regularly re-orientates and resizes the display to match portrait mode. My app is unusable in this mode so I close it down, but I think it crashes if left like this.
Edit: I'm using Dev Alpha v 10.0.9.1675 and BB10 native SDK 10.0.9.1673

I can't find an appropriate JIRA issue, anyone got 5 minutes to raise one?
My own dev environment has stopped talking to the Dev Alpha, so I can't provide much in the way of different usages at the moment.

Cool, thanks! Unfortunately, RIM are really trying my patience with stunts like:
You cannot view this issue because you are not the issue reporter or assignee, a member of the project group, or a member of the issue group and this issue is closed or in triage.
So, until it's triaged by someone suitably privileged, we can't see it. Have you included a link to this thread?
