I run a dual monitor setup and normally have a video/movie playing on the second monitor. Before the patch, everything was fine, and I could watch something while playing. But now, half the time, the second monitor comes up as a black screen. The audio plays, but there is no video. I have to alt-tab multiple times back and forth and hope that the second monitor ends up displaying something. Even then, there is some sort of "lag", as in whenever I alt-tab, the monitor freezes for a few seconds before displaying the video.
Also, I actually quite liked the feature of being able to drag the mouse cursor onto the second monitor while playing in full screen, but to each his own I guess.'
The second problem: I can't change the resolution, no matter what display I'm using, fullscreen, windowed, or windowed fullscreen. In windowed and windowed fullscreen, the resolution option is blacked out. In normal fullscreen, I can change it, but the actual resolution stays the same, and when I try to change it to windowed mode after "changing" the resolution. It's still at my normal 1920x1080 resolution.
