Completely unusable in Ubuntu 20.04

I'm seeing the exact same issues from a desktop machine. If I have one monitor plugged in directly, the second monitor plugged into the docking station works. If they are both plugged into the docking station, it is so slow as to be unusable. This behavior is different than previous releases of Ubuntu when I would have to change the pageflip Display setting in xorg.conf.d. Now, the screen draws OK, the mouse moves around just fine; however, you have to hover over an icon for several seconds before you can click it, and wait several seconds after you click it for the interaction to be registered. The same with the keyboard: even in a pico editor each key strike takes several seconds to register in the terminal. For me, the DisplayLink driver only works for 1 monitor and then only if I am directly plugged into my video card for my primary monitor. This is less than optimal for me.
