Michael Jumper resolved GUACAMOLE-483.
--------------------------------------
Resolution: Invalid
Replicating the circumstances described here, the only allocations I see
remaining are the off-screen buffers created by Guacamole to house data which
the RDP server has asked be cached (RDP's "bitmap caching" feature). This cache
is finite, and RDP will gradually free old bitmaps as the cache grows, which
will result in Guacamole freeing these off-screen buffers.
There does not appear to be a leak here.

> The issue originally occurred in an Electron application. RDP session can eat
> up to 3 GB of memory after performing a high-intensity task such as video
> playback on YouTube or just working regularly for a long time. Removing the
> Guacamole instance including the display element doesn’t clear memory. We’ve
> tried both our custom Guacamole client (clean environment), and the official
> Guacamole client.

> Possible relation to [GUAC-1134|https://glyptodon.org/jira/browse/GUAC-1134]
