My Minecraft is bugging out, what's wrong?

When I go full screen on minecraft (it happens worse in full screen) it goes buggy and flashes white every now and then as if its having a seizure. When I walk to signs they flash as well, but when they flash they go invisible, and I can see the coding behind them. Other players flash too and I can't even see myself in F5 mode

I think it is only one server this happens to me in, but nobody else in the server has this issue?

Someone know what to do? Thank you

Added (1). EDIT:
As it turns out it isn't only one server. Thanks, and along with the sign problem - it also happens to chests.

You could try lowing your graphics and anti alliasing in your setting from minecraft

Well, update your display card. It usually helps.

If it's only one server, it might be a plugin issue

What's the server and I can test it? Or you can go on mine and test that either
