[QUOTE="agarzola, post: 736110, member: 69578"] Thought I'd give an update… Shortly after macgig posted his/her suggestion, I created a test account and logged into it immediately, using fast user switching. The iMac *did not* like that. The entire dock was a big mess of seemingly random pixels (not too different from the messed up areas of the screenshots above), and a Finder window would only move smoothly if I kept it away from the lower quarter of the screen. As soon as I moved the window closer to the bottom of the screen (near the dock), it would start lagging severely, until I moved it back up. This makes me think that it may have had something to do with the reflection that shows on Leopard's Dock surface when windows move close to it. So, I'm inclined to think it's a video card problem, indeed. Anyway, when I logged out of the test user account, the screen went blue (the same hue as one would get behing the login screen in previous versions of OS X) and that's when it beachballed indefinitely. Ten minutes later, I had to force shutdown the computer. After turning it back on, everything seemed smooth again (as it usually does, at first) and so I left SoftRAID take care of some rebuilding it had to do while I left the apartment for a few hours. I returned about six hours later to find the computer still in good shape (perfectly responsive, no lagging or tearing), and I thought I'd give it a test run. I worked on a small job I had to get done by tomorrow, using Photoshop, Illustrator and InDesign (all CS3), with Linotype FontExplorer X, SoftRAID and Transmission all running in the background (as well as Quicksilver, ted and Plaxo). Use of Photoshop included scanning some medium-sized images, I did some live tracing in Illustrator and handled a few large TIFFs requiring high quality previews on InDesign. The computer has remained very responsive, with no lagging or tearing whatsoever. I finished the job, generated the final files and sent them to my MacBook over my LAN to send to the client over email later on (Mail on my iMac has been buggy ever since the Leopard upgrade… another issue I've yet to figure out). All seems to be well for now, and the iMac will remain turned on for the rest of the night while SoftRAID finishes rebuilding some disks. I'll report back here as soon as I have news. harryb2448: Thanks for the tip! I'll certainly look into that if I run into further problems.
