Problems

Frame Issues in Blue Sphere Game
When the game lags, it is possible that it will duplicate or show the wrong frames in the wrong order. This is most evident in Blue Sphere; where it will happen when there are any number of spheres on the screen. In order to avoid this, enable "Emulated CPU Clock Override" and set it to 150% or higher. Refer.

Various Minor Graphical Issues
While playing through the 2D Sonic games, you may see some visual oddities here and there. Spikes spawning in out of nowhere, certain objects not rendering right away, or flickering on the Act 1/2/3 text. To fix these issues, you can enable Safe Texture Cache at the expense of performance.
