I use avatar pictures and "auto size" is enabled but "ignore size for row height calcs" is disabled, to get bigger avatars pictures.
After miranda startup (lates dev version) it always hides contacts in the bottom side and i have to scroll down to reach and see them.
The next time something changes (user goes offline or comes online) it is correct again and nothing is hidden anymore.
It would be nice that it displays all correct straight after startup.
