Dominik Borkowski commented on GUACAMOLE-1363:
----------------------------------------------
[~vnick]: Yes, the problem goes away. It's interesting that it worked just fine
under 1.2.0 with glyph caching being enabled, as we set only a couple
non-default options. Is this an issue specific to 1.3.0 stable tree, or can we
expect it to continue with next release?
With our setup we use the same config to serve hundreds of connections to
different images, so I'm concerned that disabling glyph caching may result in
degraded desktop experience for our users.
Thanks!

> 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[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!
