JRiver Media Center 20 for Mac works great with OSX Yosemite; however, when scrolling through the files list I get annoying bright flashes. The flashes don't appear in any other apps. Not sure if its a bug from Yosemite or MC20.
I tried redundantly selecting 100% scale in the view menu, so far no flashing!
I had not tried it nor noticed it on Mavericks and I do not see anything like this on Yosemite
