   It seems that this happens only if done repeatedly… (Maybe images are not released correctly?)

   If the app run out of memory, then it means that a reference to the bitmap is kept somewhre. The createImage function does not keep a reference itself, so this means that a reference is kept elsewhere by the caller. JavaScript is known to retain a lot of references due to closures. Could you share your script (or a fragment to isolate the leak) ?

       var img=LL.createImage(view.getWidth(),view.getHeight());

   
   

       var c=img.draw();

   
   

       view.draw(c);

   So it depends on what you do with the result of screenshot(). But yes, if d is a desktop, these images will rapidly consume a lot of memory.

   I’m now manually recycling the bitmap after use, it helps a lot.

   If you can recycle them without a crash then it also means the bitmap is not drawn anymore but that probably means also that the reference is still kept somewhere: it will leak a lot less memory, but the leak is still here. If you need more investigations I can use tools to look for leaks.

   Is it possible to free (like in C) a reference, or to unlink all reference of an object? (so it can just be deleted from memory)

   Special for bitmaps there is a specific call: bitmap.recycle()
