[LMMS-devel] QT4 == slow

[Paul G. <dr...@gm...>]

Notice the conditional if.  I'm not sure if it is QT, or if it is our use of
it. But QT4+LMMS = Horrifically slow.  I mean, I move windows and the sound
starts chopping even though CPU usage is well under 10%.  Odd eh??

Well, it seems to mostly be from moving windows, so I suspect it is
QWorkspace.  Trolltech is going to drop QWorkspace support in the future, so
I am changing the code to use QMdiArea and QMdiSubWindow.

I will let you know how things go.  Hopefully Javier isn't already doing
this :)
