Description
So I have two monitors: one is a 144Hz monitor, and the other is a 60Hz monitor. Everything is set up correctly and I properly get 144Hz output in games, other applications, and on the mouse cursor.
However, if I drag windows around on my 144Hz monitor, I'll notice that their movement is limited to 60fps. If I disable my 60Hz monitor, only then is the same behavior is rendered at 144fps.
Monitors: Acer XG270HU, Acer P215H
GPU: GTX 1080 with proprietary drivers
OS: Arch Linux 64-bit

Research direction
No file or test is named. Start by reproducing window dragging with a 144Hz and 60Hz monitor connected on Arch Linux, then trace Cinnamon's window movement and rendering path. Done means windows on the 144Hz display move at its refresh rate without disabling the 60Hz monitor.
