How to disable graphics hardware acceleration globally for all applications Because this affects all applications on the system, it may cause performance problems for some applications and some applications may not run at all. The solution is to disable any hardware acceleration in the application that is playing the video or disable hardware acceleration system wide. This problem affects all screen capture programs, and even the image put in the clipboard by the Print Screen key. Most video capture programs which capture video from a video camera use “hardware overlay” by default for their video preview. Graphics hardware performs a “hardware overlay” of video on the screen, which bypasses the normal Windows display memory that Snagit captures. Newer media players normally use graphics hardware acceleration on your system. The problem is actually not related to Snagit but usually due to graphics hardware acceleration being used to display the image/video. Have you ever tried to capture video with Snagit but instead of getting the video you end up with a black or grey screen?
