Does anyone else have issues where, upon opening folders in Finder, nothing shows up (i.e. the contents of a folder)? Sometimes the files do show up, but the text is this distorted, bolder version, and nothing is clickable? Whether the files show up or not, I can still use cmd+a, cmd+c, etc. to move files around. The only workaround I've been able to find is just using killall Finder in Terminal whenever it happens, and having the folder already open when I do it. I've been having this issue since around the GM release of Yosemite, and a complete reformat and reinstall of the final Yosemite release has not solved the issue.
