Public bug reported: I experienced the same issue reported in https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1724307 on my Dell XPS 13 (9350) running Kubuntu 18.10 (4.18.0-25-generic) with KDE Plasma 5.13.5. My laptop was connected to the 2nd monitor using the VGA port on the Dell 4-in-1 adapter with the DisplayLink driver 5.2.14
I followed the comment in this link (https://github.com/DisplayLink/evdi/issues/29#issuecomment-479529359) and mannually added /usr/share/X11/xorg.conf.d/21-displaylink.conf file with the content below: Section "Device" Identifier "DisplayLink" Driver "modesetting" Option "PageFlip" "false" EndSection After rebooting, the mouse no longer flickers when connecting to the 2nd monitor using the DisplayLink adapater so I think it could be a solution for this problem.
