Roman4604, have you tried the following to fix the judder?
Disable SyncPlus which you will find in SmartHub (probably last page of app's). Also be sure to locate the terms and condition setting for this application and disable it. Firmware 122.2 installed SyncPlus as part of the update - 1023.2 did nothing to fix the issue.
P.S. You can find the terms and condition settings in the Privacy Notice section, just uncheck "Agree". Along with disabling it, streaking/blinking/random lines across screen should cease!
