Title: RenderWindow size with Windows scaling
Post by: azyryanov on July 11, 2018, 11:06:07 am

Hello.

I'm making a game for Windows. When I set Windows scaling to 150%, SFML RenderWindow is not scaled accordingly. Moreover, if I try to run my game in fullscreen mode, it occupies only 2/3 of the screen. Is this a SFML bug, or am I missing something?

I'm using SFML 2.5.0, Windows 10 with latest updates, Nvidia GeForce 970 with recent drivers.

It's a problem/bug with how SFML announces DPI scaling and (mis-)handles window (re-)sizing. If you've built SFML yourself, look for WindowImpl32.cpp, there's a function setProcessDpiAware(). Make it return on the very first line (basically skipping the remaining code) and see if that fixes the issue or what changes.

Thanks for the tip, it helps.

Does this problem/bug has a Bug ID? Or should I create a new one?

There's an issue/PR somewhere, can't find it right now, but it's basically a known thing.
