If I enable the cache in imp/config/backends.local.php (I'm using the  
advanced IMAP server)

$servers['advanced']['cache'] = true;

the seen/unseen status of messages in the folder summary doesn't  
always reflect the actual IMAP flag status (see attached picture, in  
the stable version of IMP 6 all messages in the Virtual Inbox should  
be marked as unseen). For most messages, it is correct, but sometimes  
messages are incorrectly marked as unseen.

The attached screenshot was made by going to the folder where I store  
all Horde related mail, selecting all messages and then marking them  
as unseen. Immediately afterwards, the messagelist is displayed with  
all messages as unseen (as expected). If I now go to another folder  
and back to the Horde folder, it looks as if I didn't change the flags  
as it shows exactly as before.

After logging out and logging in again, all messages from this folder  
are now listed in the Virtual Inbox (as expected). But the seen/unseen  
status is as before, some are marked as seen and some as unseen. In  
the stable version of IMP this should not be possible, as all messages  
in the Virtual Inbox have the unseen flag set (otherwise they wouldn't  
be in the Virtual Inbox), so the status must have been cached somewhere.

If I then go back to the Horde folder and mark all messages are seen,  
the messagelist shows all messages as seen (correct). But if I go to  
another folder and then back to the Horde folder, the same messages as  
before all this is marked as unseen (as if the flags were not changed).

After logging out and logging in again, there are no more messages in  
the Virtual Inbox (as expected), but the seen/unseen status in the  
messagelist still shows that some messages are unseen and some seen.  
By the way, this is not random, each time the same messages are marked  
as seen.

If I disable the IMAP cache by

$servers['advanced']['cache'] = false;

this doesn't happen and the seen/unseen status as shown in the  
messagelist always follows the actual IMAP status.

I use the following cache settings:

$conf['cache']['default_lifetime'] = 86400;
$conf['cache']['params']['driverconfig'] = 'horde';
$conf['cache']['driver'] = 'Sql';
$conf['cache']['compress'] = false;
$conf['cache']['use_memorycache'] = 'Memcache';
$conf['cachecssparams']['driver'] = 'filesystem';
$conf['cachecssparams']['lifetime'] = 86400;
$conf['cachecssparams']['compress'] = 'php';
$conf['cachecss'] = true;
$conf['cachejsparams']['driver'] = 'filesystem';
$conf['cachejsparams']['compress'] = 'php';
$conf['cachejsparams']['lifetime'] = 86400;
$conf['cachejs'] = true;
$conf['cachethemesparams']['check'] = 'appversion';
$conf['cachethemesparams']['lifetime'] = 604800;
$conf['cachethemes'] = true;
$conf['sessionhandler']['type'] = 'Memcache';
$conf['sessionhandler']['memcache'] = false;
$conf['memcache']['hostspec'] = array('localhost');
$conf['memcache']['port'] = array('11211');
$conf['memcache']['weight'] = array();
$conf['memcache']['persistent'] = true;
$conf['memcache']['compression'] = false;
$conf['memcache']['large_items'] = true;
$conf['memcache']['enabled'] = true;
