TEXT object cause black screen after OS 18.104.22.1682.
I am sure the same app works well with text object before updating OS yesterday.
My Playbook got a black screen if an app has text object on current layout,
when I remove all text object, anything works.
Will there be a next OS update to repair this problem soon?

After a whole day debugging, I still can't explain what happened now.
I made a simple file to test if text object only cause the bug,
this .bar looks ok.(window scale ratio is 480x640)
So I changed my original app's window scale ratio from 320x480 to 480x640, text object works without blank screen.
(before this, I have to remove all text objects to made other things work.)
But I still want my app's window scale ratio is 320x480,
so I tried to change the window size to 640x960 (2x). Text objects work with a 1/2 performance.
Then I tried to force the layout grow its size in game per 3 seconds,
like what I made in the zips below for download,
when the size get to 2x (means the screen performance come back to what I original want it be),
I prepared 2 zips for test.
This one is the crash one.(start the game and wait the layout become it's double size.)
This one is the same file without text objects. works very well.
By the way. You can start the game and wait to the music finish and start loop.
It will cause the sound volume of playbook forced to be max. That's the second bug in zip.
And some special sound like the ball hits the brick, audio display twice while I just play once.
(Music or longer sound like TryAgian seems normal.) It's the third bug in zip.
However,so far I can make my game mute, but can't easily make my game without text object,
so I hope the text object problem can be fixed soon.
I am sure that the text object is normal before last OS update,

Though official docs of BB said that playbook support webgl,
after testing for several days, I am sure now if you turn webgl on,
you can't use any text object without crashing on BB app.
