Under certain conditions the keyboard inputs become "queued" when trying to write something on the desktop, this causes two main issues:
1. Inputs will not only register in the target field, but will sometimes register in Steam Chat, this is a serious security and privacy concern when typing in a password or other sensitive information.
2. Inputs will sometimes double, this usually happens when closing out of the dashboard before the inputs are finally registered.

The conditions under which this happen seem to be numerous and I'm not exactly aware what all of them are, however the one I'm certain of is the network adapter being overloaded, when I transfer files to/from my NAS, which will usually max out the network adapter's 1Gbit bandwidth, keyboard inputs never work, I'm not exactly certain why that is a cause for this but if the keyboard inputs are going through socket-based IPC that might be why.
