When I tried to stream using OBS (capturing my monitor and a standalone window of Minimeters at the same time), I CAN’T SEE MY MOUSE POINTER DIRECTLY INSIDE THE WINDOW OF VITAL. I can still see it in my OBS window. Once I stopped capturing Minimeters, things got normal.
I’m using the default skin, so it has nothing to do with the skins. But I’m using a cracked version of Minimeters 0.8.23 (don’t tell others pls), so it’s an interesting feature though. 
Minimeters costs 10 usd and afaik has no copy protection, you can’t be using a cracked one since it doesn’t require a crack.
