MacOS Sierra Performance

Hallo, I have recently installed driver for DisplayLink version 2.6 from the download section. It seems the drivers seems to be buggy with many problems on Sierra. The second monitor has a laggy mouse and some of the images doesnt seem to appear on safari or photos. When i exit full screen mode from a video, safari keeps crashing and refreshing everytime. Also mission control doesnt work correctly, mission control previews cannot be seen and screen just hangs for couple of min when i enter mission control. I have already raised a bug report on apple site , but i don't know when it will be resolved. Kindly could you check and solve this issue as soon as possible. Regards Rahul

Reduce transparency 

Try going to System Preferences > Accessibility > Reduce Transparency > [CHECK] Stability is very good on my Mid-2012 MacBook Air so far.
