Hi,

one of my beta testers had a problem with my current game when he switches to fullscreen mode:

The buttons are draw using SetViewport and TileImage. Here is the code snippet:

SetViewport(viewportX, viewportY, viewportW, viewportH)
TileImage IMG, X, Y, frame
SetViewport(oldViewportX, oldViewportY, oldViewportW, oldViewportH)

Any suggestions how to fix it (I cannot reproduce it on any of my machines).

I don't want to be Captain Obvious, but SetViewport does not work properly on some [usually older] hardware.

I see. Thank you for the info.

Do you know of any workarounds for this problem?

Make the buttons a full image and draw them normally. I know it sucks you have to change the way your gui works for this, but it's the only way to avoid the hassle.

OpenGL? You could try ShareGLContexts() if it is... (call it before initializing the video)

@CzarFlavius: Yeah, the problem is that the width and height of buttons / windows will be automatically calculated and filled with a repeated texture. So, saving everthing as image would have the disadvantage that I need many differen pictures for various sized buttons / requesters.

@Slotman: I will try that. Thank you.

You can tile them manually. It will just be awkward.
