Ok, so I run vim inside of tmux and recently (today in fact) I suddenly can't use ctrl+hjkl to switch between panes in tmux and vim, instead it just makes the bell sound and refuses to switch.
If I select the tmux pane with the mouse I can switch back to the vim pane using ctrl+hjkl but again can't switch back out unless I use my mouse ( I know, I know).
The problem only occurs in the pane that has vim loaded in it.
In my tmux.conf I have:
# smart pane switching with awareness of vim splits
bind -n C-h run "(tmux display-message -p '#{pane_current_command}' | grep -iq vim && tmux send-keys C-h) || tmux select-pane -L"
bind -n C-j run "(tmux display-message -p '#{pane_current_command}' | grep -iq vim && tmux send-keys C-j) || tmux select-pane -D"
bind -n C-k run "(tmux display-message -p '#{pane_current_command}' | grep -iq vim && tmux send-keys C-k) || tmux select-pane -U"
bind -n C-l run "(tmux display-message -p '#{pane_current_command}' | grep -iq vim && tmux send-keys C-l) || tmux select-pane -R"
bind -n C-\ run "(tmux display-message -p '#{pane_current_command}' | grep -iq vim && tmux send-keys 'C-\\') || tmux select-pane -l"
and I have the following keybindings set in my vim config:

and becuase it might be important my dotfiles.
EDIT:
Holding ctrl and pressing h makes my cursor move left and doing the same but with l cuases my cursor to blink into Nerdtree and then it immediately blinks back to the main text buffer.
The same thing happens with j and k except it moves the cursor down and refuses to switch upwards.
