[Dhabud (dhabud2003)]

i started seeing this after upgrading to mythtv 0.26. OS 12.04. Upgrading to 12.10 did not help.

It happened in the middle of showing a programme on a second display.

We really do appreciate you opening this ticket to help improve Mythbuntu, but it needs to be closed for a number of reasons. The biggest one is that upstream has moved on to a new version and believes this to be fixed. Could you please verify if this issue still exists in the latest version?

Please do not let the closing of this ticket dissuade you from opening a new ticket if this (or any other) problem occurs with the newer versions.
