Since upgrading to Displaylink 5.1 or 5.1.1 from 5.0.1, when the Macbook Pro is in clamshell mode, there is overall system (app switching, general use) and keyboard input lag (typing faster than it shows up on the screen) that makes the computer nearly unusable. If I open the lid, the lag disappears entirely. This lag was not present in clamshell mode with version 5.0.1.

There is also another issue that was present in 5.0.1 and still persists. Sometimes keyboard shortcuts will stop working momentarily. For example, opening a new browser tab with COMMAND+T, or pasting with COMMAND+V. It will then start working again and then the behavior will happen all at once as if it was blocked and was queued.

Please let me know if I can provide further details or help debug this issue. Thanks.
