Description

I am using guac to get home.
From the guac UI, I open a full screen RDP to my desktop.
From my home desktop, I am then opening /another/ RDP session within my existing RDP session.

 

When I do this, typing out stuff comes out very strange in relation to the shift key and this seems a consistent fault, specifically causing issues with passwords utilising the shift key.

THIS IS ME HOLDING DOWN THE LEFT SHIFT KEY

 

I do not know the cause of this, it's a pretty obscure problem, but it's specific to guac.  It's like the way guac forwards a shift key is not persistent?
