Re: [Traverso-devel] recent traverso release

[Nicola Döbelin]

Hi,

I'm the maintainer of the OS X/intel port, so maybe I can clarify some things.

Thanks A LOT for pointing that out. I almost thought we had to live without 
plugins on OS X for a while, as I had no idea where to start looking for the 
bug. I'm relieved that there is a simple work-around.

These actions are indeed a lot slower on OS X than on Linux. In fact on Linux 
they are super-smooth in my experience. I always thought it was the poor 
painting performance of Qt, but then I realised that [G] + ScrollWheel is much 
smoother than [G] + MouseMovement and that the painting, although being worse 
than on linux, is not that slow either. I have an idea where to start looking 
for the problem, but for now I can't help you there, sorry.

Support for embedding icons in the title bar (which is standard on OS X) is 
relatively new and somewhat unstable in Qt. I can disable it and create a new 
binary. The only downside is that it looks less 'macish'. Alternatively, you 
can try the following:

1. Open a Terminal from the Applications/Utilities folder.
2. Navigate to the location where Traverso is stored, e.g. "cd Desktop"
3. Start Traverso with the following command:
   "Traverso.app/Contents/MacOS/traverso -graphicssystem raster"

In that mode the traditional toolbars are used and your problem with fullscreen 
should not occur. Plus the overall painting performance should be significantly 
better. Please let me know if you see any improvement.

> I'll report more as I have time to use it.

I appreciate your help. In fact I hardly ever use the Mac port. I just happen 
to own a Mac, but I'm running Linux on it most of the time. So I rely on user 
feedback to find minor bugs.

Thanks again.
Nic
