After upgrading from TB 102 to 115, I've noticed that the message list now flickers when scrolled and takes some time to fill the missing lines.

And also after Help > Troubleshoot Mode?

How many messages are there in the folder?

Comment 3

[Emmanuel Bourg]

There are 16000 messages in this folder, but I observe the same phenomenon on a folder with 4000 messages.

It's slightly different in troubleshoot mode:

• when dragging the scrollbar, the list turns mostly blank until the movement ends (so less flickering but no display)
• the slow filling is less visible when dragging the scrollbar, but still perceptible when moving the mouse wheel

Emmanuel, are you still seeing this?

Like bug 1858208?

Comment 6

I don't know, I've downgraded to Thunderbird 102. Which version should I try now?

Comment 7

115.8.0 is the current version https://www.thunderbird.net/en-US/

Just tested with 115.8.0 and it's still flickering. I'm under the impression it's a bit faster when scrolling, but the slow reflow when the scrolling stops is still the same.

If you using imap, and are able, please try beta https://www.thunderbird.net/en-US/download/beta/

Is there a zip package that I could install without messing with the installed TB 102?
