Preview improves but still horrible in 10.10.3

[smithrh]

For some reason, I couldn't search effectively on these terms, so I decided to back up and load 10.10.3.

Well, Preview is indeed better, but still un-usable. On a scale from 0-100, it goes from 3 to 7. It opens my file (PDF) better, but as soon as I zoom in, one of the cores goes to 100% CPU usage, and stays there, making any subsequent re-sizes or moves incredibly difficult.

Yes, I filed a bug report on this, and I even gave them the file for a benchmark. There's nothing wrong with the file, it behaved perfectly in Preview pre-Yosemite.

Oh well.

The highlight function is broken for me.

just checked, and both of these things are working fine here, so something specific to your setups... (am running 10.10.3...).

What model of Mac are you running 10.10.3 on?

What model of Mac are you running 10.10.3 on?

I have a large variety of them, save a Mac Pro.

It's not a model-specific issue.

The reason I ask is because I have Yosemite installed on 3 Mac Computer, 2011 iMac, 2009 MacBook Pro and 2009 Mac-Mini and have not experienced any issues with Preview. I thought maybe it is related to retina display Macs.

Preview performance is definitely worse in OS X Yosemite. I've noticed that as well on my 27-inch iMac (Core i7 3.5 GHz, NVIDIA GeForce GTX 780M). It's definitely not the hardware...
