I am currently experiencing a bug which causes my game to "reload" occasionally when I switch between windowed and fullscreen mode using the F11 key.

Upon entering fullscreen or windowed mode, my monitor will turn black for several seconds before proceeding to reload Minecraft.

Proceeding this event, I will experience increased input lag as well as Geforce Experience not properly displaying appropriate text but a black box. The best way to resolve this issue in the short term was to restart Minecraft. 

I am fairly sure that my monitor is not the issue, neither is my computer because then my monitor would indicate that my display input was off. I have no explanation of why this occurs and am neither sure whether this is an issue affecting others. I will admit that I do switch between the two modes frequently (due to the lack of a second monitor) though I do not switch between them quickly.

I am unable to provide any photographic proof of my issue at this point of time.
