I realize it's kind of pointless to be bringing up bugs at this point, but I'm curious as to whether anyone can explain to me what's going on here.....
 

 
This is typical of the kind of weirdness that seems to accumulate in my Sonar projects the longer I work on them. 

I've seen similar weird ones in the past. They went away after I updated the graphics card drivers.

Damn, I just recently updated mine, lol.

Before or after the issue? Sometimes a backward step can be successful.

Usualy video card related. Stuff like that always happens here.

Whenever something like this shows up, I seem to recall reading that people that experience it report that they are using an nVidia card and it's after a driver update.
Are you using an nVidia card?

 

I've always had issues like this crop up in projects, regardless of which gfx driver I've had installed. In this case, I'm at a loss as to understand why a driver issue would draw a slow curve fade like this where none exists in the project. Sonar has always had a number of weird UI issues and I think we're too quick to blame graphics cards, especially given that I use a whole host of other software with UI's and none exhibit this kind of behavior. My card is a Radeon HD 7700 and it doesn't give me problems anywhere else. 

I feel the same way, James. I have had graphical issues with SONAR that I don't have with other software, even using common as dirt integrated Intel graphics.
 
Thinking about it recently, I found myself wondering if the "theme-ing" in SONAR has anything to do with it, and if I might get different results with different themes.

Could be in some cases, however I've seen these weird graphical glitches in Sonar since way before the introduction of themes. 
 
I believe one of the reasons why Sonar is so buggy is because its bugs are so random and hard to pin down. You often see weird stuff that you don't have a hope in hell of replicating to a recipe, and so there was never any chance of the Bakers getting to the bottom of it (unless the bug description gave them an "aha" moment which was immediately apparent, of course). 
 
As an example, last night I was in the piano roll and had entered four quarter notes, one after the other. Later I went back to move the first note up in pitch, and when I clicked on it, all four quarter notes were combined into one long highlighted note. But when I dragged it up, it turned into a quarter note again. Classic Sonar "wuh?" moment, lol. 
 
Another seemingly unfixable bug was with the track manager. I would sometimes spend ages tidying up a project by hiding all the stray tracks I didn't need, only to find those tracks become randomly unhidden when I loaded the project again. Saw this mentioned on the forums a few times as well. I also had the occasional MIDI track completely disappear from the project. I'd hide it, and go back to it later to find that it wasn't there at all. Had a couple of people tell me the same thing had happened to them, too. There were a ton of problems in the console as well - I sometimes had tracks completely missing from the console view with no way to get them to reappear, even though I had that track type selected in the console view settings. 
 
It depresses me that these infuriating, workflow killing bugs will never be fixed now.

I wouldn't give up hope quite yet. I don't know anything, but Gibson needs money, and I believe Cakewalk brands (SONAR, Z3TA+, Rapture, etc.) still have a lot of potential value.
 
I would be really surprised if competitors aren't looking to acquire all or some of those assets.
