When attempting to work on a project (old SD footage in an .avi file) after several minutes of work, especially when scrolling along the timeline, many of the thumbnails randomly disappear, and then whenever I play video I hear audio but the preview screen does not show any video. When I save close and re-open, it's fine, for 30 seconds and the issue returns.
