Wierd mouse on menu

Hi all,
when i get raceroom started, my mouse is way off the menu, on the right screen it is, so i have to alt-tab and back to have the mouse on center page to clic menu. i have a triple screen setup and yes in all others sim the mouse is correct.
is there a way to stop this issue?

 

No one has a clue?

 

I'm still asking around to see if anybody has had the same issue, but nobody came forward so far... :/

 

Do you have raceroom in fullscreen mode or borderless windowed mode?

 

In full screen

 

Hmmm... Can you try borderless windowed mode? I used them both before without issue's on a triple screen setup.

 

Sb else suggested it might have to do with Windows' built in scaling feature. In your Windows display options, under scaling, do you have something else than 100 %? Maybe that messes with the coordinates somehow...

 

I will try in windowed mode borderless and report back

@Christian Göpfert

its at 100% allready

 

i tryed in windowed borderless and it works but R3E spans only on the center and right monitors.
its wierd, i cant move the window.

 

Have you setup triple screens in the launch parameters?

 

No, i must admit i did not understand how to do it.

 

That is probably the reason why.
Do you know how launch parameters work in steam?

 

yes i know witch tab on the properties, only i dont know what to write as a launch parameter for triplescreen there.

 

All is explained here.

 

Thanks a lot
