IMAP synchronization question

gmail recently turned on CONDSTORE support a few months ago for 
everyone, rolling it out over time. This may have changed how 
Thunderbird synchronizes gmail significantly.  There is a UseCondStore 
pref set on the incoming server.  You can try turning it off and see if 
things go back to the way they used to work.

Ah, he were go after some googling, bienvenu says on

gmail recently added support for condstore. You could try telling 
thunderbird not to use condstore (it's a hidden pref, setting 
mail.server.default.use_condstore to false will turn it off for all 
servers). The partialuidfetch is done when we use condstore, so if 
turning off the use of condstore fixes the issue, that would be evidence 
that the partialuidfetch is involved.
