I'm having a problem for some time now. Every time I start my pc I have this graphics bug

Notice how the border is transparent and you can see everything through it. Then I have to go to personalize, color and set the color of the window and then it looks like this

Notice how the window is not grey and not transparent.
And I have to do that every time and you can imagine it's really annoying. I've reinstalled graphics driver few times and I've no idea why is this happening. So if anyone can help I'd really appreciate it.
