    Hi

    I am having an issue with a new app which we just launched on the App Store. It is a simple painting app. I understand that the “painting brush strokes” are made out of circles in the code. Randomly, every so often a stroke will appear as a few squares instead of circles. When this happens the “start again” button does not clear the canvas completely. It will clear all paint brush strokes that where made with circles but it will leave on the screen/canvas the stoke that was created by squares. The only way then to get rid of this then, is to delete the app and re-download it.

    The occurrence of this is very random. You have to be using the app for a good few minutes before the square strokes are randomly made. I wasn’t aware of the bug until I tested the app with some kids!

    Any help much appreciated – as I mention this app is now live on the app store so I am trying to get a solution quickly.

    Thanks so much

    is this problem happen with corona simulator too?

    if it only occurs on iOS device, can you find any errors in the console of XCode?

    It seems something causing out of memory. In the setting of kwik panel, turn on show memory used in the terminal
    and I think the problem would not happen easily on corona simulator but you can check the memory consumption in the terminal.

    Please try to find out which user actions or factors making memory leak.

    Hi Yamamoto

    I have tried to simulate the problem on Corona Simulator. But the problem only seems to be on the device. I has tested it on three difference iOS devices and same problem on all of them.

    It is difficult to explain the problem as it seems to happen randomly. For example I can paint for a few minutes and everything is fine, then the random square/rectangle strokes appear. Then I can erase everything except for the square/rectangle strokes and continue painting as normal, only the square/rectangle strokes will remain for the rest of the session in the background.

    I have have linked some images of the problem http://www.scribbaloo.com/technical-images/ – I hope these help explain the problem better.

    Thanks for your help.

    Reviewing the codes of kwik produced lua, I guess something causes to fail drawing circles which should be painted with square/rectangles and without the circle object, the current codes fail as a runtime error. I will send a trial fix in a few days.
