Description

This problem only occurs with 8-bit PNG images with dimensions 31 x [an odd number of pixels] and have transparent pixels. It happens when you use Image.createImage to transform an image as follows:

 Image mirror = Image.createImage(image, 0, 0, 
       image.getWidth(), image.getHeight(), Sprite.TRANS_MIRROR);
       g.drawImage(mirror, 80, 80, Graphics.HCENTER|Graphics.TOP);

When you draw the image, it will be shown with the transparent pixels of the right-hand side replaced with white pixels. If you try drawing the image several times, the phone will eventually crash.

Solution

Do not use bitmaps with dimensions of 31 x [an odd number of pixels].
