Graphics corruption issue continues in Mavericks 10.9.1
Bad news: A graphics issue reported for Mavericks 10.9 continues in 10.9.1. The drop-shadows surrounding some windows have no gradient or translucency, and in some cases, Finder windows show colored pixels in place of the content. My Mac configuration: MacBook Pro Model ID 6,2 - Mid-2010 15", Std RAM: 4 GB
Here is a screen shot, taken the day that 10.9.1 was released (December 16, 2013)
A workaround that has been posted in these threads [ System Preferences > Energy Saver > Automatic Graphics Switching (off) ] is not acceptable to me, since it reduces battery life significantly. Also, it is being reported that this workaround works only temporarily, and/or intermittently.
If you are experiencing this issue, please add to this thread. There were also reports in the Mac press that this might be one of the issues that Apple was working on for 10.9.1, but apparently not. Here's one article: http://9to5mac.com/2013/11/15/apple-seeds-first-os-x-mavericks-10-9-1-beta-to-de velopers-with-focuses-on-mail-graphics/
Here are two other discussion threads that reported the same issue with 10.9:

Let's hope that Apple is monitoring this thread and issues a dot-release quickly, rather than having us wait until 10.9.2. Apple: please feel welcome to contact me for troubleshooting, if that can help.
Thank you.
