changed title from mka qt4 gui time and seek bar move very slowly to MKV: some mka time and seek bar move very slowly

added Severity::normal label

assigned to @typx and unassigned @fenrir

Do we have the sample?

it's due to the lacing mechanism. And a real demux problem that demuxes five blocks before resetting so the time bar may advance by 40 audio frames steps which could be a lot.
