Hello. I recently installed Retro Pie, and have really been enjoying it. Recently, I noticed that the background (the blurred one) behind each system menu item doesn’t show for SNES or Sega32. It used to, but I’m not sure what changed.
I checked the themes directly, and the xml files look fine for both systems. I also grabbed the background files (snes_art_blur.jpg & 32x_art_blur.jpg) and they display perfectly on my Mac. I even replaced the following directories with fresh copies downloaded from the themes package:
Q. Some systems have a white background that shouldn’t.
A. You probably ran out of VRAM on the Raspberry Pi. A good rule of thumb for how much memory you should allocate to the GPU on a 1080p setup using the default themes is 8mb + 25mb + 10mb * [NUMBER_OF_SYSTEMS_WITH_GAMES] (framebuffer + fonts + high quality system art). 256mb should be fine for casual setups.
I had set my GPU RAM to 128, and this was the problem.
