     Type:  defect                    |      Status:  new    
 Priority:  major                     |   Milestone:  unknown
Component:  mythtv                    |     Version:  0.20   
 Severity:  medium                    |  
--------------------------------------+-------------------------------------
 Intermittently when switching between the guide and live tv mythfrontend
 will hang, and must be restarted.  This happened right after the 0.20
 upgrade, I was running 0.19-fixes before.

 Here is a mythfrontend log excerpt around the time of the problem.  As far
 as I can tell the problem always shows these messages:

 QGLContext::makeCurrent(): Failed.

   Minor opcode:  5
