New issue 81 by alexis.g...@gmail.com: game takes more than a minute to
load (slick)
http://code.google.com/p/nullpomino/issues/detail?id=81

Running slick version on linux (x86).

The game takes about 1.5min to load. During this time, there are multiple
warnings of the form "PNGImageData failed to read the data" (apparently one
per image), as well as multiple "Repeated allocation of very large block"
warning. During the loading time, java uses 100% processor. After about
1.5min, if I click on the window, the game works (almost) correctly. If I
don't click on it, java keeps on using 100% processor until I do click.
Once the game is running, transparency on fonts does not work, the whole
output is dim, and the line effect is mostly black (see attached screeshot).

More details:

Additionally, the fps also start at 60 then drop in about 20 seconds to
about 30, making the game unplayable (and java takes 100% processor). No
additional messages are reported in the console after the loading phase.
Fps go back to 60 when "retrying" a new game (without quitting the
application), then they drop back to 30 in 20 seconds.

I think it's because your initializing the texture every time you call it.
What you should be doing is having a init method like :
private void initTextures(){
Texture1 = [init texture here];
}
Then when you need the texture say
neededTexture = texture1;
