I can’t remeber specifically how it started but I think I had a couple word documents open and went back to Vivaldi then my screen started to glitch.
I was able to see and close down Vivaldi through the task bar by pressing the windows button and then everything stopped, used windows defender, turns out I had a tool on my laptop and I dont know where it came from.
But I deleted it, opened Vivaldi again and it started doing th same thing, tried egde and just opens Vivaldi. Doing another full scan now. Might I need to format my pc?
