Bizarre RDP issues with 0.9.14 / Win7
I'm about at my wit's end debugging an RDP issue and was hoping that someone
else might have seen this before and have some ideas. Our setup looks like
this:
Browser -> Page with Guacamole client iframed -> Guacamole client (not the
.war, but a custom servlet that just does very basic auth and connection) ->
guacd -> Windows 7 w/ RDP.
Upon loading the page with the client iframed, everything works just fine.
I'm able to log in and do everything in my session as one would expect. Soon
though, the image will freeze (the quickest way to get this to happen is to
go to YouTube and start watching a video). What's weird about this is that
according to Chrome's network view, requests and responses are still being
sent/received as though everything was still fine -- just without any new
data from the server, so the image stays static. To get back to the image
moving again, the page needs to be reloaded (and re-log into windows).
What's interesting about this is that inputs from the browser side are still
being sent -- so if you clicked the "minimize" button on your browser in the
frozen image, then refreshed the page, you'd see the browser properly
minimized. Everything is flowing as you'd expect, except that we aren't
getting image updates so the image remains frozen.
I've tried just about everything I could find on Google to deal with this to
no avail. This list includes:
- Disabling audio (in Windows, guacamole already has it disabled)
- Disabling autotuning for TCP.
- Disabling various services.
- Turning off the bitmap cache in FreeRDP (recompiled Guacamole to do this).
If anyone has any further ideas, I'd really be interested in hearing them!

There don't appear to be any errors. The last image we get is a jpeg (or png)
that shows part of the screen. After that, tunnel?read attempts return empty
responses, and no further image data is sent (in either jpeg or png form).

If you open up the network tab of Chrome dev tools and filter things such
that only the images Guacamole is decoding appear, does the freeze occur
right after an error attempting to read an image?

If you disable hardware acceleration in chrome, does it work correctly?

There are not. The response data (for the tunnel?read url) appears to be
empty.

Hadn't thought to try this one. Same issue though.

Do you see the same behavior if an iframe is not involved?
Are there any errors visible in the browser's console after the session
stops rendering?
