Just confirming that this issue affects me also. Here's my post from the other other bug:
I'm using Xorg with an AMD Vega 64. Both displays are connected to the GPU. My main 144hz display is connected via Display Port, and my second 60hz display is connected via HDMI.
I'm using Mesa 19.1.0-devel - padoka PPA
When I perform the test case in the first post, I get high framerates when the secondary display is disabled, and only 60 fps when it's enabled.
