32pfl4606 channels grid display performance issue

[panamea]

hi,

1. press find button on the remote => channels grid is instantly displayed
2. choose a channel, press ok

repeat steps 1&2 several times (not necessarily sequence after sequence), on step 1 you will find that the channels grid is displayed slowly row by row, from bottom-up (performance issue), as if there is more to display other than squares with channels names&numbers in it

expected behavior: always display the channels grid instantly on request (find button)

i would indicate the instant/slow appearances as 50/50, while the first display of the channels grid is always instant.
it looks like choosing the same channel (just hit ok on the same channel) helps increasing the appearances of this issue.

Regards,
Mike
