[mythtv] alphapulse caues 100% load but only on 1080p

[Warpme]

Hi *

I have issue with enabling alphapulse in themes - it causes 100% load on 
CPU one core (AMD X2 4400) .

I'm wonder is my issue somehow related to
http://www.gossamer-threads.com/lists/mythtv/users/400151#400151

All this is with 1920x1080 at 50
But If I change resolution to 1360x720 at 60 - CPU load starts to as 
expected (few %).

It is indeed related to GL painter as switching to Qt solves issue (and 
of course no transitions, etc)

I'm trying justify - should I wait till devs resolve issue desribed in   
http://www.gossamer-threads.com/lists/mythtv/users/400151#400151 or
rather my issue has other root causes...

My system is:
0.22 svn22720
nvidia 190.42
xorg srv 1.6.5
mesa 7.6
2.6.28.10

thx in advance for help
