plain terminal output

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
screenshot. Plain terminal output doesn't show anything interesting but I'm
attaching here anyway.

The problem is due to

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.
