I've also noticed general slowness in the UI sometimes accompanied by a
buzz of disk activity when the slowness occurs (no jobs running in
background). Changing to the Qt painter has made quite a difference on my
system compared to OpenGL which is sometimes painfully slow. However with
Qt mythfrontend locks up sometimes when changing channel in the programme
guide.
