Nick Couchman commented on GUACAMOLE-1363:
------------------------------------------
[~dominikborkowski]: This is covered in issue GUACAMOLE-1191, which deals with
FreeRDP's (lack of) support for various caching mechanisms, including Glyph
Caching. I don't remember if there is a tie-in to Guacamole 1.3.0, or if its
actually the FreeRDP version, or a combination of the two, but essentially
version 1.4.0 will automatically disable Glyph Caching (and a couple of the
others) due to the lack of support.
I've seen this most frequently in Server 2008, which is the same code base as
Windows 7, but occasionally on other versions of Windows.

> Hello,
> When upgrading from guacamole 1.2.0 to 1.3.0 we noticed a problem with our
> Windows 7 images: they are disconnected, then they reconnect a few seconds
> later.
> This behavior is 100% repeatable for us, and happens when:
> * user logs in, and clicks on 'activate now' or 'activate later' pop-up menu
> * user clicks on the start menu
> * user clicks on the clock on the task bar
> * user clicks on the internet explorer icon on the task menu
> Enabling debug levels on guacd shows that each disconnect with the
> `Stream_GetRemainingLength` message, eg:
> ```
> guacd[30]: DEBUG: Stream_GetRemainingLength(s) 1509 < 3342
> guacd[30]: DEBUG: order flags ff failed
> guacd[30]: DEBUG: Fastpath update Orders [0] failed, status 0

> guacd[6]: INFO: Creating new client for protocol "rdp"
> guacd[6]: INFO: Connection ID is "$8a4db747-cb8a-4675-aeab-2ea194a971f4"
> ```
> We can always reproduce this issue, but the problem goes away if we deploy
> guacamole 1.2.0. Each deployment is clean, so there's no upgrade in place.
> Our windows 7 instances are AMIs, and we can repeat this on every new
> instance.
> Any help would be greatly appreciated.
> Cheers!
