Hi,
I have a problem on windows, the viewport looks scaled and offset, the issue affects the drawing and the mouse events, the mouse position gets scaled and offset. I reckon this is not necessarily related to cinder, but it’s probably caused by Windows itself.
I did a quick test running the basic app drawing two squares, the orange rect should start at [5,5], but it’s drawn off-screen. The blue rect margin is wrong and the size is not square(roughly [150,160]).
any idea what could cause this? I’m running on windows 10, gtx 1050.
thanks
Andrea

Could the windows scaling be the culprit here? Have a look at the PR at the end of this post:

> Hi. slight_smile I’m doing: setWindowSize(854, 480); in setup(). But when I screenshot my app and measure the window in the screenshot, it’s 1068x600px. Coincidentally, that’s exactly how big the youtube player is in a maximized browser window on my PC. Return values I’m getting: getWindowWidth() -\> 854. getWindowContentScale() -\> 1 isHighDensityDisplayEnabled() -\> false My display resolution is 1920x1080 and I’m on Windows 10. Any idea what’s going on?

I’ve already tried that, it didn’t work for me.
