Horizontal graphics distortion
From Worms Knowledge Base
Running WormsDC in FS-UAE can cause some horizontal banding. The entire horizontal space aligned with a currently active object - usually the Worm in play, but also the HUD, the arrow indicating the current worm, and any projectiles or mines - can jiggle or shift by one pixel to the right. There is also some minor cosmetic sheering that occurs with the HUD. A video of the effect can be seen here.
The issue is comparable to, but significantly more severe than, a similar glitch when running the game in WinUAE. In WinUAE, this was due to incomplete or inaccurate subpixel emulation. FS-UAE does not seem to have any options for subpixel emulation.
A similar issue also occurs when playing the game on the A500 Mini, and occurs whether you're running the stock version included with the system or running the patched version via other means.
This issue does not occur when playing the original Worms in FS-UAE.
