Wrong window size on Windows 8

Hi,

I have a run-time problem on Windows 8 with SDL 2.0.3: window created is not of the requested size. For example calling SDL_CreateWindow() with width == 100 and height == 100 results in window that reports (via SDL_GetWindowSize()) dimensions 162 x 100 respectively.

Hey,

could that have something to do with the title bar requiring a certain window width?
Maybe set the SDL_WINDOW_RESIZABLE flag on window creation and see what
the smallest size you can get to is. You could also play with SDL_WINDOW_BORDERLESS.

There's a minimum windows size on certain operating systems. In this case, that's the minimum width for a decorated window, so if you really need to be that size, try using the borderless flag?

That was actually bad example on my side, I quickly checked with 100x100 to see if problem sis there too but real problem I have (my customers actually) is actually different.

Widow is being created with size 1024x768. After that checking window size with GetWindowSize() reports correct (1024x768) size. But window size is not actually that. Measuring size of inner canvas (inside borders etc) gives area of 1280 x 960. This causes problems for my customers because they have to run in 1600x900 to get 1920x1080 window.

Any ideas? That happens only on (as far as I know) Win8 btw and Intel 4000 graphics.

Wrong window size on Windows 8

On high DPI monitors Windows stretches its windows, that could cause it. If that's the case, you could see the blurry, not so sharp pixels being stretched. You can disable this behaviour somewhere in the settings.
Could it be your problem?

I definately see blurry text on my test machine. Will check the settings. It is normal Full HD laptop tho, nothing fancy high DPI.

Yes, disabling DPI compatibility helped. Thanks! I wonder if there is a way to do it programatically.

Followed this advice after yours:

I don't know if the win32 api included in MINGW or Cygwin contains the required function or not, btw. If you're using Visual Studio, then it should do.

Last time I checked I don't see any Hi-DPI support for Windows in SDL. Are we going to add that ?
