I have a problem with BGs in StepMania. They are extremely low quality (it looks like 256 colors), and it's especially apparent when the BG is smooth; there are huge blocks of colors where there once was a gradient. I can't really tell, but it only seems to affect BGs that I've made, because I don't notice any lowering in quality with the ones I've downloaded.
I make the BGs in the GIMP and when I look at them outside of SM they're high quality. I don't know if it's a problem with StepMania or my computer, or the way I'm making them. I also don't know if this problem affects other people who play my sims.
Does anybody know how to fix this? Thanks for any help.
