Hello guys,

It's been some time since I'm experiencing this issue(more than a month) and I don't know how to solve it. It appears randomly with the frequency of couple of times a week. I've included a video so you can see what exactly is happening.

There are 3 things that I noticed:
1. At the beginning of the video you can see a window appeared. However, there is no text and options are blank so I don't know what I'm clicking on actually.
2. The text in word appears blurred(not all the text, only some parts)
3. When I go back to the main screen and point at the names of the files with cursor - some of them get black and blurred.

Restarting solves the issue, but I'm getting more and more annoyed by it. I'm using Windows 10, I bought this notebook 3 years ago and even though it has Intel i7 I find it lagging a lot. Not in a way that is slow, but many times I get a message that the app is not responding and I have to wait a couple of minutes, this happens very frequently and makes me quite angry. I tried freeing some storage, reainstalling Word, defragmenting the disk, cleaning the computer with Advanced SystemCare and Driver booster 8, but none of this seems to help. Could anyone please help me with this? Thank You
