When attaching a screen on a DisplayLink device, the cursor will flicker on all non-DisplayLink screens. Additionally, the cursor will leave trails over various UI elements that update as the cursor passes (such as buttons, menus, progress bars, etc.)
The issue occurs only when a DisplayLink device is attached and driving a display. However, DisplayLink told me the issue is not specific to their hardware, and to make a bug report here.

Thanks for alerting me to the new BIOS version. The UEFI updater said it was already up to date, but I could manually install the new BIOS version from the website.
The problem is still present after the update.
