Hello all, I've been a long time Firefox user and recently (starting about 2 months ago) started seeing some irritating behavior while browsing. Firefox will at random intervals "gray out" either while interacting with specific webpage elements, or browsing specific websites. An example of this "gray out" condition is included as a screenshot. The browser will flicker between this "gray out" condition and the webpage, occasionally staying in the "gray out" state for 3-6 seconds. As you can see in the screenshot all Firefox UI elements are also missing, so this seems to be broader application issue. I've noticed this particular issue repeatedly on Amazon.com while moused over product photos. I consider myself a power user. As for my PC, it is running Windows 10. All graphics drivers are up to date. Other apps run normally. I've never had any problem browsing/interacting with similar web content in Microsoft Edge... but I heavily prefer to use FireFox. Has anyone else encountered an issue like this?
