NTSC non-interlaced mode doesn't work properly.

[IvanDSM]

Setting the "Interlaced" setting to Off on the menu stretches the emulator's screen such that only half the screen is displayed. I'm trying to use the emulator in 240p. Am I doing something wrong?

I'm using a SCPH-90XXX console with the latest release [x.3.3], connected to a CRT through component cables. I can provide a picture if necessary!
