When player sprites are hit, games will often toggle the visibility of the sprite on adjacent frames. So on Frame 1, player sprite is visible. On Frame 2, player sprite is invisible, and on Frame 3, player sprite is visible, and so on.
The NES displays at around 60 frames-per-second, and any deviation from this on the computer's monitor will likely occasionally produce a dropped frame in the emulator. When this happens once in a while, or on an irregular interval, it will not cause the sprite to disappear entirely, but the flashing effect might be more choppy than normal. When it happens on a regular, frequent interval, such as every other frame being dropped, the player sprite will disappear entirely or be entirely visible for an unacceptable length of time.
On Windows, make sure that you have your video output device/card manufacturer's drivers installed. Microsoft does not ship hardware-accelerated OpenGL drivers with Windows for some reason, so installing the vendor- or manufacturer-supplied drivers should help.
