Windows 8.1 Blank Lock Screen

Hi guys,

I am new to this forum and would like to enlist your help with regards to a problem I've been having.
A month ago I upgraded to Windows 8.1 (my computer started the upgrade automatically) and since then I have been having problems with my lock screen.
When the computer powers on, the lock screen is just totally grey (windows theme color) but with the icons (Ease of Access, Internet Connection, Power Options) still visible below. When I press a key or click on the screen, I am able to type my password and log in as per normal.
I was wondering if anyone here has a fix for this issue? I know it is not very major but I would appreciate if you guys could help me resolve it.

Thank you!

What happens if you try to assign a different wallpaper/background to the lock screen?

Yeah try going into pc settings and select a picture for your lock screen.

Another vote with Wallpaper.

Thanks for your reply, that was the first thing I tried when I encountered the problem and it doesn't solve it.
I'd like to add that this happens occasionally, and sometimes my lockscreen wallpaper would be normal while other times it would be grey (as mentioned)
I've poked around the forums and read that it may be a switchable graphics issue? My computer does have switchable graphics and it has given me some problems in the past but not until I've upgraded to Windows 8.1 has this problem surfaced.
