Blurry/pixelated icons at random in Finder windows

Just upgraded my MBP (C2D, 3GB RAM) to SL, went smoothly. I'm seeing a lot of blurry icons in the Finder, though, seemingly at random. I'll open a window and about half the icons will be essentially large versions of the 16x16 icon, rather than sharp icons at the appropriate size. Changing the icon size via the new slider just enlarges the blurry icon, it doesn't increase the resolution.

It goes without saying that I'm seeing this on programs, files, and folders for which high-resolution icons is available.

I haven't seen this mentioned elsewhere. Is it a common problem? Surely it'll be addressed in a forthcoming update, but I wonder how rare it is. The only oddball thing about my system is that I have an older ADC-connected 23" Apple Cinema Display monitor connected to the DVI port via Apple's behemoth of a DVI->ADC adapter.

Thanks,
Eric.

I'm not sure if anyone has mentioned this or not, but this problem seem to happen when OS X needs to create (or update) an icon. For example, whenever Chrome updates itself, its icon gets pixelated (see the attached image). Likewise, whenever I install a new application, its icon is pixelated. The only solution, albeit a temporary one until it happens again, is to reboot.

So this weekend I finally got around to rebuilding my Mac's system from scratch, in addition to the app icons, this system wouldn't save preview icons for new image files saved from Photoshop and other apps, was really slow, other problems, etc.


So: clean format, brand new Mountain Lion install (previous one had been an upgraded system from Lion), start to selectively re-build app installs and account data. Things are snappier, but every single app store download comes with the lo-res icons. Every downloaded .DMG, same thing. The icons seem to fix on re-logs or restarts, but still annoying.


So today I installed the developer preview of Mavericks, seeing as how I've got fresh backups of everything. Icon problem is fixed. App store downloads, .DMG downloads, all of it.

I have Snow leopard OS 10.6.8,


MacPro3,1

Processor Name: Quad-Core Intel Xeon

Processor Speed: 2.8 GHz

Number Of Processors: 2

Total Number Of Cores: 8

L2 Cache (per processor): 12 MB

Memory: 10 GB

Bus Speed: 1.6 GHz

Boot ROM Version: MP31.006C.B05

SMC Version (system): 1.25f4


Apparently I can't upgrade to Mountain lion because the processor won't work well with that OS system. Is that true? Will I need to buy a new computer? I don't have the money right now. It probably won't do any good though to upgrade it to Mountain Lion, as the blurry icons seem to still linger in Mountain Lion. Has anyone had any success in upgrading their operating sytem, as far as the blurry icons go?

for all that is good and right PLEASE DONT DO IT ArtistGirl ... I have nearly the identical set up as you (Mac 3,1, 2x2.8 Quad-Core Intel Xeon, NVIDI GeForce 8800GT) except I have 16 GB of DDR2 RAM ... Lion ran nice and fast on my machine, as well did Snow Leopard, but the installation of Mountain Lion became the bane of my computing existance .... I would have gone back to Lion but my backups became corrupt after the Mountain Lion install. Its been a complete nightmare ... just food for thought ... we both have the minimum requirement machines and my experience has been awful too say the least ... PLUS all the wonderful pixelated icon issues still exist in all their "glory"

The CS6 icons are fine under Mavericks on my iMac.


I was seeing the Finder icon issue with my fresh ML install, so for me, at least, it wasn't because of CS6. I also have CS6 on a MacBook Air running ML, with no problems, either with preview icons or .dmg/app icons.


I think the bug is related to a certain vintage/combination of hardware, which is a theory I think I've seen posted on here before. I would be very interested if someone else with the bug is able to install Mavericks on the affected machine.

Alas, if it were that easy a fix, there probably wouldn't be 29 pages of people suggesting different things in this thread.


Sad to say, but I'll bet my right procesor core it will come back for you. Just plain rebooting fixes the blurry icons for me every time. But, like undead pixels of screen resolutions past, they always come back. Usually within an hour.


I've given up for now and am just begrudingly living with zombie icons that look like they're from 1995 in the "world's most advanced operating system" of 2013. I just have to keep my shotgun terminal.app at the ready in case one shambles up and tries to bite me.
