Hi,
Thank you for posting your query on Microsoft Community.
From your issue description, I understand that scroll bar/slide bar disappears after a few seconds.
To help you resolve this issue, Could you please answer the following questions.
- On the scroll bar, you need to perhaps tell us where you are in Windows 8?
- When you have this issue; are you somewhere on the Start screen or in a Windows 8 store-style app or are you somewhere on the Desktop side?
- Where are you missing the "scroll bar”?
Please answer these questions so that I can rectify your issue as soon as possible.
You know where the problem is your, just playing stupid! Its on Windows 7, 8, 10, etc. You haven't got that yet with everyone posting queries to you? The issue happening on my PC is just about every where i go. the start at my settings, different web sites,you name it. I disappears while i'm using it and sometimes as soon as i get it back up it will disappear before i can even click it. My scroll bar is on right and i have Windows 10. Maybe that will give you the info you need to correct the annoying problem that i and lots others are complaining about.
