I am using window 7 64-bit
Very often, I will have this visual defect problem on my screen like below:
As you can see, there is a
Save as Ctrl+Alt+S
floating on my screen.
This problem happens when I save some files.
The occurrence is random.
I solve this problem by restarting my PC.
But what could be the possible root case and how can I solve this defect without restarting my PC
