That's the cause of this I've seen with most games.

What setting do you have to change to make it appear?


DXDIAG is a program you run from a command prompt or the Windows start menu 'run' dialog box (or 'search programs' in Windows 7 or later). After running it will open a window and start collecting info with a progress bar in the lower-left corner. When it completes click the 'save all information' button and save it to a file then attach that file here.

Please send in the game log C:\Users\<UserName>\AppData\Local\Introversion\Prison Architect\debug.txt

To see the AppData folder you'll need to enable View Hidden Items in File Explorer.
 
Interesting ... is that f.lux or some other app?
 
I went into my pc settings and set it all back to default.

Me too, once Flux was fixed up it was cool to reset the other things. I actually haven't noticed the "blinding cursor" either, so that's been ok.

Yeah. It was a really weird find. It would be really great if you could patch this also....mice problems are super weird and hard to diagnose and super shitty to deal with in general :D.
