Welcome to the forums SneakyRobot.
That strange skewing problem you described, seems to happen
with certain vst plugins.
And it would sometimes happen to me, with the Dsk OranZe plugin too.
From what I've noticed, I think that turning certain dial(s), on the
Oranze plugin, causes that strange skewing problem.
Sometimes it would happen, sometimes it wouldn't.
I remember at one time, whenever I turned a dial, located on the
lower bottom right of the plugin, the strange skewing problem
would reoccur.
I solved it by closing the vst plugin, then removing the vestige instance
from the song editor.
Then from the left side bar, where all of the lmms plugins are located
I dragged in/re-imported vestige again, into the song editor, and re-imported
OranZe from it. And that helped solve the magnifying/skewing problem.
If my tip works, please tell us. I hope it works for you too.
