6680 image data loss in game

[Gorky77]

On my MIDP1 game image data seems to get lost on 6680, on NGage, 6630, 6600, 7610, 3650 etc it works fine though:

the character and other images get crippled as u see in this image

what could cause that??

The 262K colour display of the 6680, perhaps?

it should load 8bit png with arbitrary palette and sample colors on internally though

As far as I know no phone uses palette's internally (Except maybe the old Siemens S55, as it ONLY supported 256 colors). The image is probably loaded into memory and kept in the native format, for faster drawing. So having a large image suddenly using 256K colors instead of 65K will make a difference. Maybe it uses 4 bytes pr pixel and since the phone dont have much more memory it will cause problems.

We also have some issues with 6680 and I'm sure it is all to do with the same issue.
