I have an AMD Radeon RX Vega M GH Graphics.
I open any video on YouTube in Chrome and go into full screen mode. Then I click RMB and start moving the mouse cursor over the context menu items. The video does not play smoothly (a lot of dropped frames) + the YouTube interface blinks Here is a good example: https://mega.nz/#!TEs0zAYL!fR71p6JDfLaQbW4QOJI-Sy0yX1wQKbTjZJrMzY4JPVAhttps://mega.nz/#!TEs0zAYL!fR71p6JDfLaQbW4QOJI-Sy0yX1wQKbTjZJrMzY4JPVA
In Firefox, everything is smooth and without any problems What is even more absurd is that after launching "Action!" (program from the Polish company "Mirillis") this problem disappears What the hell is going on?! You can also get rid of this problem if you open the chrome://flags/ page and choose "D3D9" or "OpenGL" instead of "D3D11" for the "Choose ANGLE graphics backend" option At first I thought the problem was in Chrome. But many others do not have this problem in Chrome!
It seems that the problem is in the AMD Radeon graphics driver.
