Hi I have a really strange and annoying problem since I reinstalled windows as you can se in the screenshot here:

there is something running (litestep.exe?) that takes up space of the taskbar and in the popup, but it doesn´t show in alt-tab. I have tried different builds but the problem still remains...
It wasn´t like this before I reinstalled everything.
