Reply To: Theme backgrounds not showing for some systems

[Sumpy]

Disregard. From the FAQ:

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.
