vim-airline takes 100% CPU when open condfig.src file

[vijayandra singh]

1. Install vim-airline package on 24.04
create config.src file
[vs@cf4:~/dev_git/freertos/scratch2/freertos_sim/lwip]$ cat config.src

#SRC += $(SIMH)/sim_ether.c

SRC += $(LWIP)/src/api/tcpip.c
SRC += $(LWIP)/src/core/ipv4/acd.c
SRC += $(LWIP)/src/netif/ppp/auth.c
SRC += $(LWIP)/src/netif/ppp/ccp.c

now move cursor using arrow key up and down on around $LWIP line.
It takes 100% resources
