Daniel,
Does it happen with thunderbird started in safe mode?
- https://support.mozilla.org/kb/safe-mode-thunderbird

What changed on your system before this started happening?
How long have you been on sierra 10.12?

Comment 3

[Daniel Essin]

1 - Yes it happens in safe mode

2 - On 10.12 for 6 months. This problem appeared within the past 2-3 weels.

Wayne, unified folder misbehaving is an ancient old problem on all platforms, especially rows blanking out as the mouse passes over it.

I had that happen in my inbox for a while until I fixed it by removing the "smart mailboxes" from my profile.

So reporter, remove "smart mailboxes" from your mail storage and then configure the unified trash again.

[Jorg K (CEST = GMT+2)]

We had two reports of this lately. In bug 1342110 comment #3 I instructed a user to remove "smart mailboxes" and that helped. In bug 1342515 I suggested the same, but the reporter claimed that it didn't work. However, personally I've always been able to fix unified views by removing "smart mailboxes".
