yes

Could this possibly be that bug where sometimes, while typing in a chat or any dialogue box, a key will open up a menu behind the chat? I'm not sure what the cause is, but I just got the same thing to happen, without pressing "d" specifically.
I have had this bug occur before, however it really isn't reproducible. It happens infrequently. May just be race-conditions between textbox focus and global keybinds.
You can reproduce this by pressing two keys perfectly simultaneously.
Looked into this a bit, it's because OpenTKKeyboardHandler binds to KeyDown while GameWindowTextInput binds to KeyPress.
KeyDown is called before KeyPress.
So all that's required is for the update thread to luckily pull a new input state from the handler, and propagate that input down, prior to KeyPress being called.
Seems to have regressed.
