When I browse Facebook on Firefox and scroll in the Timeline, and hovering over a Video Post with my mouse, most of the time the website will freeze for a second, then it will flash and blink, and images in the page will disappear.
SEE THIS SCREENSHOT: https://5.top4top.net/p_1228p2h6x1.jpg
Also sometimes Windows shows a notification that says: Windows had prevented Firefox from accessing Intel GPU.
I think this issue started to happen after using WDDM 2.6 drivers.
The issue doesn't happen when using an older driver.
Please help 😢
