Comment 89 for bug 183969

The problem with tvtime reported earlier is still there with the last version. The picture (window or fullscreen) sometimes gets very dark (and distorted when corrected with brightness/contrast settings). There are no errors reported when tvtime is run from the command-line. Besides, a check with vlc confirms that it also shows a distorted picture. Reload of driver-modules for the capture hardware makes no change. The only fix is to restart the xserver. The problem doesn't appear quite as frequently with the latest xserver (Version: 2:1.3.0.0.dfsg-12ubuntu8.3), but it eventually gets in the weird state after a day or two. This points to some form of buffer corruption in a video-extension or similar. Further investigation needed.
