my computer is an Acer Aspire 7738 and Ubuntu is 12.04 LTS version, Visual boy advance is 1.8.0.
i have tried with other roms and can't find any other Linux supported emulator where i don't need Wine.

Which scaling filter are you using (under Options → Filter)?

Generally, try playing with all the available options under Options → Video and Options → Filter.

Hope that helps.

i tried every single filter and still nothing, i also tried disabling some layers to see if it were one of the layers that did it, still nothing.
i also tried Mednafen but couldn't get it up and running even though i tried everything
