While playing I will sometimes (frequently on one machine, occasionally on another) get behavior where one or both of my mouse and keyboard stop being responsive in game. I can switch to another application and have no issue using either and then switch back to Starbound and have them be unresponsive. With the mouse problem, if I move the mouse off of the game screen it appears to the rest of the system and responds just fine. The keyboard situation happens a lot more than the mouse but both happen often enough to be a royal pain. The game itself is not lagging. Animations still happen and everything in the world seems to move right along, it just stops recognizing that I'm pressing keys and/or moving the mouse. Closing the program and opening it again seems to bring things back to normal for a little while but how long that lasts is entirely random from my perspective. If it is of import, I run Starbound through Steam on Linux Mint KDE 17.3 (both at home and during lunch time at work - the input lag happens a LOT more at work, which is a slightly slower machine). In both situations my mouse and keyboard are a Logitech K270 and M570. I have no other applications that have this behavior (I play a lot of Steam games) so I'm pretty sure it isn't my setup that is causing the problem. Anyone have any ideas?
