Mac OS X 10.4.5 (#11): (Intel-specific) Screen distortion; Cursor getting "stuck"; More printer problems, fixes

Mac OS X 10.4.5 (#11): (Intel-specific) Screen distortion; Cursor getting "stuck"; More printer problems, fixes

(Intel-specific) Screen distortion Users of both MacBook Pros and iMac Core Duos have reported a problem where various bits of screen distortion are apparent with growing frequency.

We've also noted the issue in-house on a 1.83 GHz MacBook Pro.

The issue generally manifests when using Dashboard, but has occurred at other times for some users. The visual distortion looks like one or more faint discolored blocks that flicker as the cursor is moved.

We're not yet sure whether this is a ghosting issue caused by the ATI Radeon X1600 card or a software issue that Apple will resolve in an upcoming Mac OS X 10.4.x release.

Note that this is a separate issue from the video tearing problem -- mostly associated with Front Row -- that was resolved in Mac OS X 10.4.5.

If you are experiencing a similar on an Intel-based Mac, please let us know.

Cursor getting "stuck" Some users have noticed an issue where the cursor appears to become stuck at a certain position on the screen, generally after a few seconds of inactivity.

In most cases, this issue is a simple result of the "Ignore Accidental Trackpad Input" option in the Keyboard and Mouse pane of System Preferences. Having this setting turned on can sometimes generate the effect of a cursor being "stuck," as the first tidbit of user movement is accidentally ignored.

If you are having this issue after turning off this option, please let us know.

More printer problems, fixes For the past few days we've been covering some significant printer issues under Mac OS X 10.4.5, and associated workarounds, particularly with regard to Epson devices. (note that there are also several printer issues specifically related to Intel-based Macs, covered in a separate series of articles).

One workaround we didn't mention yesterday is a mainstay for most printer issues -- re-installation of printer drivers from original media or from a Web download (either directly through the manufacturers site or via a search by model/manufacturer on VersionTracker)

MacFixIt reader Jerry writes:

"My fix was to reinstall the Epson drivers from my OS 10.4.x DVD. It is now working fine."

Users also report issues with printers from other manufacturers under Mac OS X 10.4.5 (PowerPC and Intel versions) for devices that worked properly under Mac OS X 10.4.4.

Chea Prince reports an issue with his Lexmark printer. He writes:

"The same thing happened with my lexmark x83 (combination scanner/printer). lost communication with it after upgrade to 10.4.5. this is odd because i had had problems with the printer until 10.4.4. after installing 10.4.4 the x83 worked perfectly. Now nothing."

Meanwhile, some readers have noted a problem with one of the workarounds for Epson printers we suggested yesterday: using the GutenPrint (formerly GIMP print) disables the ability of some devices to print to optical (CDs and DVDs) media.

Finally, other users are noting success with some of the workarounds suggested yesterday, particularly removing extraneous drivers from the directory /Library/Printers/EPSON.

"Thanks to this recently posted tip, my Epson Printer Utility is working again."

Another reader, Frank Mullins, adds:

"Today, one of the suggested fixes on MacFixIt was to remove unnecessary printer plugins from /Library/Printers/EPSON. I did this. I worked!! The printer utility now works as it is supposed. Both printers now work without a problem. MacFixIt comes to the rescue, once again."
