My Pong game is getting a not responding warning in C++ - c++

Question

So I am creating a simple Pong game using c++ and the SFML graphics library in Ubuntu 19.04, but when I run my program it seems to work fine until around 5 seconds later, I get a warning saying my program isn't responding and the choice to wait or force quit the application. When I click wait the warning goes away for another 5 seconds but comes back up. How do I stop this from happening or is there something in my code causing this to happen?
Edit, I need this to be real time input otherwise the game uses the key repeat delay.
Edit, Discovered pollEvent did not need to be the condition for a while loop. So i put it in the main loop, This fixed it!
