I submited one bug two days ago. Only it's not confined to a single main.lua file. There may have 4 to 5 lua file you need to look into.
Look at the pictures below you will know how i am anxious.
These only happen on sony errison x10, htc G7/G10/G11, and only when you build with corona >=.640. This is under .825. If i refresh the scene(go to another scene then go back) they may dispear.
You can see the background is white blank, and some of the text are also white blank.
This picture is really weird. The img background fill with another img. when i refresh, it become normal like below.
Text may have the same problem. Text 1 and Text 3 is not show up, the area fill with text 2.
And this is a new bug of build.825
The code i submited to your bug system is not so serious(may have something to do with the number of object on the screen). Since i can't get any error report from the simulator or the device, i don't know where is the problem and how to make a simple test case for you.
