Crazy slow performance using semi-transparent images
Using semi-transparent images in LWUIT is extremely slow!! There must be something wrong with the implementation.
I have made a sample Form with a background and a semi-transparent image (24 bit PNG) in a label. A key is used to toggle the visibility of the label.
Here is the benchmark obtained on a Nokia N95:
When the label is NOT visible: 32 frame per second
When the label is visible: 2 frames per second !!
There is clearly something wrong with the implementation. There is no way I could use LWUIT in my project with such performance.
Please let me know if there is something I could do to get better performances.
I would really appreciate your help!
