Thunderbird is extremely slow with new UI update 128.3.tesr

[Sheldon]

First....  I love the over interface and functionality of Thuderbird...... However, there is extreme latency and delays with almost all activity ..... Composing /typing emails, doing bulk (delete) transactions, etc.  I am currently using Thunderbird update 128.3.tesr.

I would imagine that there are background processes that are causing these ongoing delays.  

PLEASE ADDRESS THIS ISSUE ASAP.... It is most critical for the success of Thuderbird!

Thanks, in advance, for you attension to this problem/issue!

The same here. Since the last update TB seems to lag for no reason and especially deleting mails sometimes take ages with freezing of the main-window here on Windows 10.
