iTunes 12.x (on Yosemite) display bug (scroll bars)

I am seeing a display bug in iTunes 12.0.1.26 on Mac OS X 10.10 Yosemite.

When I scroll up and down using the magic-mouse scrolling the display gets screwed up (maybe from the left-right scrollbar at the bottom of the window pane).

I am in the list view, not an album cover view.

I cannot take a screenshot with cmd-shift-4 or with Skitch because the display redraws correctly before the screenshot is captured. So I have to describe it best I can: It's chopping up some of the rows and they are getting overwritten with partial row images. Darn, it's hard to describe.

Is anyone else experiencing something like this?

Thanks,

Dan

In Transmit (FTP) when you view and scroll through a long php or css file the exact same thing happens.

Upgraded to Yosemite a while ago, but this happened in Mavericks too.

I always thought it was a bug in Transmit rather than OS X...now I'm thinking maybe not.

I have this exact problem on a 2014 MacBook Air, and none of the suggested solutions have worked over here either.

What I have noticed though is that the problem seems to get worse the more windows I have open. Closing all my other open windows and apps doesn't make the problem go away completely (at least not that I've noticed), but it does make the problem much better. With that in mind, I'm guessing it might be related to CPU usage and/or pressure on WindowServer or the graphics chips.

With Activity Monitor open and running, I can scroll up and down in iTunes, and can watch iTunes CPU usage spike to 40-45% and WindowServer to 45-48%. I have enough applications open right now (along with a large secondary display) that WindowServer seems to be working at 25-30% CPU usage all the time. Add these usage spikes to the combined usage of all the other open apps, and this leads to the CPU itself, or at least one core, being pretty much maxed out while scrolling in iTunes. No idea how much, if any, of this is actually related to the problem.

This also doesn't give me any real idea of how to fix it ourselves, as it seems like it might be an OS level problem...

It is the OS where it's not refreshing when scrolling with a mouse. I'm seeing it across all sorts of applications - iTunes, Mail, MS Word, BBEdit, VMWare...

Ho hum.

I fixed this by switching to iTunes 11. I love having the sidebar available all the time.

I have the same problem and as it has already been written, it doesn't happen in full screen mode.

I've had the same issue recently. What I found was that it occurred if there was a horizontal scroll bar appearing when scrolling vertically. Narrow your columns on iTunes or remove the unused/unnecessary options and that has solved it for me. Dropping it to small list size will help some, just depends how good your eyes are 😁
