Screen turns white

I thought it was a new computer, so I returned it and got another one. It still happens.

On some forums more than others. The text comes up and then disappears after one second. The heading and ads are still there; it is the topics and replies which disappear, leaving the center of the screen completely white. It is just the writing that goes away.

Has this happened to others? What makes it do this? And what can I do to fix it?

TIA

What browser and OS are you using?

Do you have this problem in alternative browsers?

Maybe not the OP’s problem but I read about a bug in Windows 10, I have not had time to look it up, I don’t use 10.
