Homebrew consoleInit(): Displays nothing if not used; displays weird triangle if used

[delete12345]

This is what it looks like if I specified:

consoleInit(GFX_TOP, &topScreen);

I know consoleInit() will change the frame buffer format to 16-bit, thus creating this glitched out triangle.

However, when I changed consoleInit() so that it outputs messages on the bottom screen, and I specifically do not do anything to the top screen, I get nothing:

I pretty certain it will be the same if I run this on my n3DS.

May I ask what is wrong with my code? Thanks in advance.

gfxSwapBuffersGpu() should fix your problem.

TRIANGLE? IT MUST BE THE ILLUMINATI!

No but seriously, that looks pretty interesting.

gfxSwapBuffersGpu() should fix your problem.

It didn't work:

Did you replace gfxSwapBuffers with gfxSwapBuffersGPU, because the only reason I see for that black screen is a double buffering problem unless the app crashed. You can try disabling double buffering with gfxSetDoubleBuffering(GFX_TOP, false);

Yes I did. Still no dice.

EDIT: Apparently, just re-ordering gfxSwapBuffers[Gpu]() and gfxFlushBuffers() around makes the triangle appear!

Sorry for the large image size. I have no idea how to scale them down.
