OSD with Heroes of the storm

For some reason the OSD is jumping around on screen. It doesn't want to be in the corner, sometimes in disappears and when I try to use chat in game, in pops up in the middle next to the chat box. It works fine on the main menu just not during gaming.

 

Change the coordinate space from viewport to framebuffer in RTSS.

 

That worked, thank you.

 

Thx for the tip unfortunatly I have to change it in the global config, why I can specify it only for a specific game ?
