Since I can't find a way to comment on the bug that I opened and was closed almost immediately < https://sourceforge.net/tracker/?func=detail&aid=2999543&group_id=192583&atid=941981>, I thought I would post this issue to the Skim users list to see if anyone else has noticed it and/or has a workaround. Maybe I was wrong to classify this as a bug (as hofman seems to think), but I didn't know where else to put it—this didn't seem like a feature request when I originally posted it.
To summarize, I recently bought a new MacBook Pro (released April 2010 with the i5 and i7 processors; relevant to the following issues is that they switch between built-in and discrete graphics cards on-the-fly, and noticed that using the Search PDF function (Option-Command-F) in Skim causes the more powerful discrete card to become active. Also, the discrete card also stays active after both closing the search pane and closing the PDF. Having the discrete card on uses more battery, which is not something that I want to happen on a laptop when just reading a PDF. The source of the graphics card switch is any use of Core Animation (CA); in Skim, CA is used to display the graphical transition to the search results pane after using the Search PDF option. Other people have noticed the switch with apps that use CA for small UI features < http://discussions.apple.com/thread.jspa?messageID=11449395>. It may be a bug on Apple's end that the more powerful graphics card *always* gets invoked when CA is used (I have sent feedback to Apple regarding this), and maybe they will fix it for cases where the discrete card isn't really needed like in Skim's case, but maybe they won't. To get to my point, I don't know much about creating GUIs and using CA in OS X, but I wonder 1) if it is really necessary for Skim to display the search pane transition using CA, and 2) if it is possible to make using CA transitions an option. I'm not being angry here, by the way. If it is imperative for Skim to use CA for the transition and making CA transitions optional is not a possibility, that's fine, I just want to know. Thanks for developing such a great PDF reader/annotater. I hope to keep using it while running on my laptop's battery! Best, Matt
