I play on a 34" monitor with 2560x1080 resolution. Since the last update I now get a blurred smear right in the center of the screen, vertically from top to bottom. I tried to get screenshots but the screenshots are in a different resolution and do not show the problem.
This is a real problem because the blur/smear looks just like a cloaked phantom so I keep shooting at what is essentially nothing.
Second problem is that my weapon sounds keep disappearing.
