1nsane is an off-road racing game released in 2001.
When the graphical option 'skid marks' enabled strange artefacts are flashing
across the screen. They are flashing so rapidly that I couldn't take a good

Reverting the patch fixes the problem.

Steps to reproduce the problem with the demo:
1. extract and install the demo.
2. start the demo with Game.exe. In the menu choose Single Player > Quick Race
> Start Race. Graphical option 'skid marks' is enabled by default so you should

see the visual glitches as soon as you start racing.
