Here you can find my support file:
The system is an AMD Ryzen 2400G with integrated AMD Vega11 Graphics.
Emulationstation menu looks like Vsync is off. As well SNES and Megadrive judder and Vsync style artefacts are on screen.
Dolphin is totally unplayable with both renderer-types Vulkan and OpenGL and sound is very slow.
With beta 5.27 20200811 Dolphin runs wonderful with Vulkan.
It seems that something is broken for AMD GPU users after 20200811 release.
