In WinUAE, the sprites for worms, projectiles, mines and in-motion gravestones are shifted to the right by one pixel, resulting in an inaccurate representation of the object's current location. Once the object has stopped moving or is no longer active, the sprite shifts back to its "real" location. This issue is still present as of WinUAE 4.0.0.

An extreme version of this glitch is also present in FS-UAE, a multi-platform Amiga emulator - the entire horizontal band of the display - terrain, mountain background and all - is shifted by one pixel to the right. This is also present in the GUI, suggesting the possibility that WinUAE is not accurately displaying the wind and weapon power levels.

Curiously, this glitch appears to affect sprites at the half-pixel level. The Amiga's native "High-Res" mode halves the horizontal width of pixels, resulting in rectangular pixels and more horizontal detail. WormsDC uses this mode on the menus, but does not appear to use it in-game. It's therefore unusual that WinUAE and FS-USE would render this error at a High-Res pixel depth, unless WormsDC is doing something sneaky with the screenmode. Further investigation is required.

This glitch also affects the brush in Graffiti mode.
