[CS 1.6] [BUG] Strafe and disappear smoke

[perforatorRU]

If you throw the smoke and make a strafe from behind the wall, the smoke disappears for a fraction of a second, but it's enough to get information about the enemy. An example: https://www.youtube.com/watch?v=04tt4ejNBBE

The P.S. bug is only at this location on the de_tuscan map. Maybe on other maps, too, but we need similar conditions.
