In the picture, the bug was soft.
When this bug decides to show up, those frames happen to appear all the time and some transparents squares appears in graphics (like picture).
I believe this is some opengl rendering problem and the game (Day of Defat. A Half-Life1 modification) itself.
I've already tested all possible drivers (Omega/Catalyst).
This problem just happens with this game and others Half-Life 1 modification.
With my old PowerColor X1300 HM512mb (Catalyst 7.6) I had no problems with it.
Does someone have a clue?
Just a driver issue (as always with ATi, right?). try to switch to Direct3D mode, as far as i remember, this is possible in half life and its modifications. This may help
