@pablo mamrmol
I assume you either use Deere or LateNight skin.
The issue you reported is another symptom of lp:1746475 and lp:1746110

Both are fixed with https://github.com/mixxxdj/mixxx/pull/1512
Please test! Instructions to do so using 'git' are here:

ronso0, I tried your skins-waveform-CPU-fix branch and it works!, the log file maintains a normal size.
Bug fixed. Thank you.

(and yes, I'm using the LateNight skin)
