@hellomiakoda That was my guess. Go fire up Tuba on Linux on a desktop and watch how much memory it consumes.
As the timeline scrolls, I don't think it releases memory, I think that scroll list just continues to grow ad infinitum.
I like Tuba (and could tolerate the memory voracity), except for one other bug - it timeline jumps when live streaming is enabled, which drives me _bonkers_
Anyways, that's my guess on your memory issues, cause yeah, 6 GB should be enough; it is on a desktop.
