Bash Version: 4.4
Patch Level: 20
Release Status: release

Description:
I am using Microsoft Windows-10 -wsl ubuntu.
when dubugging c++ codes having extension .cpp via gdb debugger, I observe
that TUI does not get rendered properly.
But when I use the same code and binary in ubuntu-18.04 LTS, that I have
dual booted alongwith win10 in the system
the TUI works flawlessly. Please correct the same.

Repeat-By:
1. write a code say, main.cpp
2. compile using g++
open cmd
wsl
g++ -g -o main.out main.cpp
gdb
tui enable
file main.out
l
set breakpoints using b main.cpp:<line_number>
r (run the programme)
n
info local (tui breaks at this point)



Fix:
Using ctrl+l after every command works always.So, I tried hooking majour
commands like next,continue, and info local
to refresh command, but that does not works, always.
