I have MacBook Pro on Big Sur (15-inch, 2017 Radeon Pro 560 4 GB), Dell D6000 and 2x Dell P2721Q 4k monitors.

When I'm connecting these monitors directly with USB-C cable everything is smooth and animations are working correctly.

When I'm connected through Dell D6000 both 4k displays are unusable. It feels like 10fps, every animation (moving windows, scrolling, anything what cause any change on screen). It is totally unusable. I was trying different DisplayLink Manager versions but on every version it is the same.

Should Dell D6000 be fully operational with such monitors on 4k resolution or do I need to change dock?

On my previous setup with 2x Dell 1080p monitors everything was working correctly without any lagginess.
