Finder images blurred
I have had this problem ever since I got my MacBook Pro. The images in Finder often get pixelated and blurred. I really need to fix this because I work with images and need to see the thumbnails clearly. Here's a screenshot of what it looks like:
This problem lasts for years, and while earlier it happened occasionally, now I get that every day. Relaunching Finder doesn't help, only rebooting the system, but the problem pops up almost right away, so restarting isn't really helpful.
I have the OS X 20.6.8
I would appreciate any help!
MacBook Pro, Mac OS X (10.6.3)
