I have the same problem and I'm running Thunderbird on Windows 7 x64. Previous major version (78.X) worked without a problem.

When moving the mouse cursor over the emails in the message list pane, the highlight effect considerably lags behind the cursor (similar to the video posted by the reporter). Checking the Task Manager shows two Thunderbird processes jump to a combined CPU usage of 60-80 % (the first process takes 50-70 % and the second between 10-20 %).
