Helloo guys.
I have a problem with the game, but I think it's not a bug so it can be solved manually, I just don't know the way.

After every battle a status is added on the top of the screen (which shows you time remaining etc, like the potions you drink) which is a skull.
The problem is that from the moment it appears, even if it disappears after 30 seconds the screen has a green surrounding and it's blurry and flashes every 2 or 3 seconds.
It seems like the character is poisoned, but Geralt's health does not drop at all.

Do you know what might be happening?
PS: Unforunately I cannot take a screenshot but I will try.

Try using fraps to take screenshots it should be free if you dont need any advanced function.

It is not a graphics problem as it might look, it flashes and becomes like this every 1 second because of the potion thing

EDIT:
Ok, I just found out that it is activated every time I use the adrelaline bar (button X, to kill many enemies at once)
A screenshot from when it's activated

If anyone knows the solution please post
