Just after the update I first noticed weird behavior on YouTube, by pressing F the screen kept flashing the fullscreen video. Pressing the arrow keys gets the video player constantly fast forwarding.
Since then I checked and this also happens when pressing F5, the browser keeps resending the F5 command, keeping the tabs constantly refreshing. This happens to every key press on every site, somehow typing still works but there's and odd delay when typing into a text box.
