I have a similar issue. When I press the remote, it takes 100% CPU for 2
seconds and then it goes to the next item.

When I press fast 3 times, then it takes 2 seconds and then jumps 3
items at once.

It only happens with high resolution (1920x1080), so I did not think
it's a LIRC issue.

Then I updated from X server 1.3 to 1.4 and now navigating is very fast
again, but every 8-10 items, it pauses again for a few seconds and takes
100% CPU, before it continues.

So, it's better, but not solved.

Using the QT painter, it's always slow.

Now I am thinking, it's an X server or OpenGL issue.
