Hi! Just recently all of a sudden started randomly getting a black rectangle that cover the right size of the main screen, it looks kind of like the notification sidebar but it's a about 20-40px thinner. It covers everything at all, as in it's always on top of any other application. Notification sidebar is openning and it's also mostly hidden under this rectangle. Right clicking it opens right-click menu and shows just one entry "Copy". I'm not sure but I think it kind of looks like metro-style right click menu as opposed to desktop-legacy style.

Restarting PC did solve it once, but now it just shows up again after restart. I tried shutting down processes one by one and it finally disappeared after restarting Explorer.exe. I did not have a chance to go through all the processes though so maybe it's just connected to it. I did go through things like nvidia everything, dropbox, nextcloud and a lot of stuff that integrates itself into Explorer though and it did not help.


What could it be?


EDIT:

Turns out it only disappeared visually but it's still blocking any clicks in that area. Ffs

EDIT2:

Damn it, found it. Slack. Wtf...

is it still happening?

Try a clean boot and see if it changes anything - make sure to read instructions and make sure NOT to disable any microsoft services or windows won't load right - https://support.microsoft.com/en-au/help/929135/how-to-perform-a-clean-boot-in-windows

if clean boot fixes it, it shows its likely a startup program. You should, over a number of startups. restart the programs you stopped to isolate the one that is to blame.

Tried running malewarebytes and see if its malware?
