I was trying to play this game, never realized i had it for a very long time. When I try to play it, pixels flash all over my screen. Anyway to fix it?

Screenshot?

ok wait

You can't see it in a screenshot i've tried, but yeah there is pixels on the screens. I think it's because the game is very old so it's just ♥♥♥♥♥♥ up with the new computers.

I have same problem. When I had the game downloaded from official website, not from steam, everything was fine. Laptop was the same for both versions. I recorded a short video of this problem, I'll try to put it on my profile and check this Legacy mod.
Update: Legacy fixes the problem and adds better resolution, so it's good solution
