Resuming from standby (i.e. the APM state just above hibernation in power consumption), the savage X.org driver has broken overlay. The result is that kaffeine/totem/mplayer all show blue/black displays stretching the full height of the display and fail to show any video. Audio is played back just fine.

The only workaround is to reboot/logoff or to Ctrl-Alt-Backspace out of X.org. Logging back in then allows playback to continue without issue. The last entries in /var/log/Xorg.0.log are :

dmesg output is not available as a lot of network traffic has been passing through this machine today. That is not related to this issue and this issue is reproducible without such a strenuous day :)

I'm not sure what other information would be of use.
