Windows 10 on 4K monitor, resolution problem

Hi Guys.

Running my apps on my 4K monitor is a real pain.

I set the preferred size to 1920 by 1080 and it works perfectly… for a while.

After an hour or so of work, suddenly the display starts to be modified by the windows desktop scaling.

So in my case it suddenly becomes roughly 2560 by 1920.

The back buffer remains the same size, you can see the pixel scaling, but the window is suddenly much bigger.

When it starts to do this, that’s it. It never goes back.

Anyone else come across this?

Haven’t come across this myself but maybe your app.manifest is telling Windows to deal with scaling your app instead of letting you handle scaling yourself?
