If you've overclocked anything, check your voltages. this error also pops up if you're low on system memory, despite it not really alluding to that. check to see if there are processes consuming a lot of resources.
This happened to me three months ago .. if you are using amd driver then don't use the updated version. There is a video in YouTube I followed regarding the same issue and I finally solved it .
For anyone with this problem, it is caused by gpu drivers/gpu crash. Check drivers and if that doesn't solve it, rebooting does wonders for this problem.
Clearly, the problem here is you are taking pictures of your screen with your phone. Press F12 and you'll take a screenshot.
Don't ever, under any circumstances, take a picture of your screen with your phone.
