Screenshot paste only works in some apps, not in Google Chrome

Solution 1:

I've seen this kind of behaviour with other functionality, try the following command in Terminal (may require sudo)

Change directory to "/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/"

cd /System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/

./lsregister -kill -seed

OR

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -seed

This rebuilds the launch services database, sometimes corruption in this can cause weird behaviour

EDIT: Since the above didn't help let's try something else. When you use shift+control+command+4 to copy a section of the screen to the clipboard you can view the clipboard contents. To do so, switch to Finder and click Edit > Show Clipboard to show the contents of the clipboard. You should see something like this window pop up that says "Clipboard" at the top and has a description of the clipboard contents in the bottom-left corner. Do you get the same thing?
