This stretched bug only appears on "Intel HD Graphics 530" card.

Only in windowed mode.



See "Bug.jpg".

I get the exact same issue on Tier 1 on my Dell Precision 7520. Intel HD Graphics 630 similar to yours.
Windows 10. Nvidia Quadro M2200.

This one's been bugging me for a while. I posted a comment about this on the development thread about a month ago and it got very little response. I hope it gets looked at as I often work windowed at least to start with and this makes windowed apps useless.

baxslash,
When you turn your graphics card to Nvidia Quadro M2200 it's fine, right?

I use a workaround for the stretching, although my stretching appears in windowed fullscreen. I create my images and text with a virtual resolution of 1280x720, and the window is set to 1280x720. I get devive max width and max height and store them in variables. I then set the virtual resolution to device max width and max height, but every time I want to modify any of images or text, I set the virtual resolution to 1280x720 and when I am done (and before I sync() ) I set the virtual resolution back to device max width and max height. Use GetMaxDeviceWidth() and GetMaxDeviceHeight() as the one without Max in the command names gets a smaller section of the screen taking into account stuff like the taskbar. My plan is to store all changes during the main loop, and then at the end modify all images and text in one block so that I only have to change virtual resolution twice.

EDIT: For me, this happens when using a resolution of 1440x900 which has an aspect ratio of 16:10 instead of the usual 16:9 and therefore has a differently sized backbuffer.

It's not the way Cybermind.

I hope TheGameCreators will fix that bug. Because every other game (not-AGK) works perfectly on that graphics cards.

Not sure what you mean, that is the one I am using and I have the same issue.

baxslash,

On the notebook that I used, it was the bug only in "Intel HD Graphics Mode" and it was fine when I turn to GeForce card.

I thought it was already the default but it actually wasn't. You have just saved me from giving up on AppGameKit for a while!

baxslash,

AGK doesn't support new (2-3 old) Intel HD Graphics "cards" well.
It is a really big problem for me, and I have no responding from AGK-team...

Guys, I had the same issue on my Dell and this is clearly a graphics driver bug, I've got it solved, damnit if I only knew how... Let me check...

edit:
Look here: Bug Report for Intel HD
and here: https://developer.blender.org/T51521

Other software is affected as well. Solution for me was to update the Intel HD graphics driver with at least this one:
https://downloadcenter.intel.com/download/27058/Graphics-Intel-Graphics-Driver-for-Windows-15-46-?product=96551

Probably best is to use the latest one:

So my workaround was not even needed, it was an Intel driver bug??? Thanks, this will improve performance in my game ( = Will try this when I get back, my bug only appeared on my Intel GPU as well, I thought it was because of the obscure resolution my screen on that Intel GPU uses.
