This "glitch" almost always happens with a browser window, but sometimes it happens with an Outlook email message. I click or tab away to some other window, do stuff, then come back to the browser window. I point my mouse at a link, and click to follow it. But instead of following that link, the page scrolls up 2 lines and the click is delivered two lines below where I was pointing, often on some other link I didn't mean to click on. It happens on Linux. It happens on Windows. It happens on OS/X. It happens with Firefox. It happens with Chrome. It happens with IE. It (sometimes) happens with Outlook. It happens whether I am running the program directly on the native OS, or through a remote session, or in a virtual machine. But it doesn't always happen. Only about half the time. It's extremely maddening, and I can find all kinds of bug reports about this to the websites of open source software involved: Chrome, Firefox, Ubuntu. But no solutions. Anybody else afflicted with this glitch?
