Windows fullscreen is black

[brinoausrino]

When starting an of application in fullscreen mode under windows 10: the screen turns black.

When toggling from fullscreen to window mode by keyinput everything works like expected, the screen shows the correct picture.
Using ofToggleFullscreen() and ofSetFullscreen(true) produce the same result. This only occurs when switching the screen mode without key input.

Starting in OF_GAME_MODE works as expected

Thanks for the report @brinoausrino
Just to confirm is this with the latest OF release 0.9.3 or is this with the current master in github?

[brinoausrino]

Has been with 0.9.3 and with the master branch like 2 weeks ago

@brinoausrino
I just tried the empty example in 0.9.3 on Windows 10 and did the following:

//========================================================================
int main( ){

    ofSetupOpenGL(1024,768, OF_FULLSCREEN);         // <-------- setup the GL context

    // this kicks off the running of my app
    // can be OF_WINDOW or OF_FULLSCREEN
    // pass in width and height too:
    ofRunApp( new ofApp());

}

it worked as expected.

If you do the same - do you still get a black screen?
Was it working for you on Windows 10 for a while and then stopped working ( wondering if a recent Windows 10 update could be the issue )?

Any more info would be helpful.
Does your system have a dedicated GPU like AMD or NVIDIA?

If you have an Intel GPU did you try installing the latest intel GPU driver?

Just letting you know, I just tried the same on my Win 10 machine, in both debug and release mode.
Both worked as expected.

thanks @rwebber I'm guessing its an issue with Intel gpus. Does your machine have a dedicated graphics card?

[rwebber]

I only have dedicated nvidia.

Ok, the driver seemed to be the issue. I am using the onboard graphics card. Everything worked like expected. But now another issue occured:

My screen runs in portrait mode and when entering fullscreen the software seems to switch to landscape mode. Manally forcing the mode by of SetOrientation() did not help because the software seems to crop the image.
Even more interesting is, that when I am using 2 screens and focus on the non-fullscreen screen the picture looks absolutly right. When I then focus back on the fullscreen, it the looks strange again. I attached 2 photos of the issue (the rendering is rotated by 90°). First I made a screenshot, but in the screenshoot everything looked alright.
Hopfully my explaination is not to confusing (since the issue is).

fullscreen

windowed

Does this error occur only with the Intel onboard graphics or with external graphic cards too?
