Thanks for posting this report.
The problem it's not a known issue on Mac.
Is the corruption visible on a screenshot of the DisplayLink screen? Please use cmd+shift+3 to grab the screenshot and check the resulting image files on your desktop.
In case it's not visible in the screenshots, could you please upload a photo of the DisplayLink screen showing the corruption?
Do you use the DisplayLink screen in mirror mode or extended mode?
Could you also please grab the DisplayLink logs using the debug tool here, while running 2.4 driver and when the problem is visible:
Mac Debug Tool
and upload the output file here or send it through
http://support.displaylink.com?
Thanks for your help!
