While using even the latest build on my 650D I have experienced trouble getting the shutter angle and shutter speed to display properly in the UHD 1x3 crop. I have been using the 16:9 aspect ratio, but I don't think that is important. When I use the buttons to adjust the settings, they do change (image becomes darker/brighter), and the "TV" followed by a number also changes (e.g. TV 5.6). I think it normally gets locked up while displaying 1/29 and 299 degrees. wondering if this is unique to my camera or if it is a known issue.
