Memory and waveform

feedback:
I use MLT files as clips - which allows me to handle smaller source files.
In the file that brings together the MLT clips, if I leave the waveform displayed on the clips, the memory saturates (until shotcut crashes)
Waveform activated in the timeline: memory full at 98% and processor at 95%
Without waveform enabled, memory 17%, processor 3%…
