We have an application that uses png images with transparency. On Nokia 2700 we noticed that some of the images are not rendered correctly.
The same set works fine on other S40 nokia's (checked with quite a few) it seems that transparency is not handled correctly.

The artifacts are visible on edges and with light colors (i.e. gray on white).
I have not seen anyone reporting similar problems except that one

http://discussion.forum.nokia.com/fo...d.php?t=182325 which was on nokia 6212c.

This bug refers to svg. We also tried svg and seems that the same artifacts are visible.

We have tried many png formats truecolor w alpha, indexed, 8bit 24bit, BMP 32bit and seems none are free of the problem.

Do you know what can be the problem? This phone has unusual display (with a kind of glass protection which makes screen 2mm).
