Mouse cursor lag when using the UD-ULTCDL to connect my monitor

[DockHaver]

Hello! I will try to summarize the situation.

I’m using a 16" macbook pro, one of the intel versions, running Catalina (this also happens on Big Sur)
My mouse is a Logitech MX Master 2S connected to the laptop via bluetooth
I have one device plugged into the dock, which is a 4k LG 27" monitor. The dock is then connected to my laptop via USB-C.

Problem: the mouse cursor is lagging on the external display. More precisely, the cursor does not move smoothly on it, it is as if the monitor has low ‘frames per second’. If I move the mouse onto the mac’s display, it moves smoothly with ‘high FPS’. If I connect the same monitor to the mac using the USB type C cable, everything is smooth - this problem only happens when using the dock.

Anything I can try? It is annoying enough to not be able to use the dock, unfortunately.
