I cannot reproduce the issue. I have just installed Mixxx 1.11.0 on Ubuntu 12.4 64 Bit.
And the memory footprint stays constantly at 76.5 MiB since one hour.
Please verify that the you select a "empty" Waveform from preferences and both spinnies are off . Than restart Mixxx and check again.
Please try to start with a fresh database. This cane be don by rename the hidden folder ~/.mixxx. Mixxx will create a new one when started.
