[No Bug]Fullscreen vs Windowed

[Bate]

I have a GUIWindow and an GUIImage, the image is a child of the window and is positioned so that it shapes the upper and lower arbitrary border of the window. the inside part of the image is alpha transparent (this part is exactly where the window is positioned).

Code: Select all

IGUIWindow *windowOptions = guienv->addWindow(recti(100,100,700,500), false, L"OPTIONS", 0, GUI_WINDOW_OPTIONS);
windowOptions->setDrawTitlebar(false);
windowOptions->getCloseButton()->setVisible(false);

IGUIImage *windowOptionsImage = guienv->addImage(driver->getTexture("data/window_options.png"), vector2di(0,0), true, windowOptions);
windowOptionsImage->setRelativePosition(position2di(-1,-10));
windowOptionsImage->setNotClipped(true);

in fullscreen it looks precisely as intended. only in window mode it looks distorted. (using Direct3D9)

FS: correct


Windowed:


I guess basically it's not the best way to achieve what I want, but it's pretty easy like that and works fine in FS. I'm not sure if it's a "real" bug or a concequence of the implementation though; but maybe it is possible to do something about it?

It seems that you have more than those errors, check the fonts of your screenshot. They're also distorted. Which image dimensions do you use? What's the exact render code?

The image is 602x420. Hm do you think the image not being a power of two causes the distortion? Then why does it work in FS.

Code: Select all

while ( device->run() )
{
  if ( device->isWindowActive() )
  {
    cameraUpdate( smgr->getActiveCamera() );

    driver->beginScene(true, true, SColor(255, 0,0,0));
      smgr->drawAll();
      guienv->drawAll();
      myCursor->drawCursor(20);
    driver->endScene();
  }
  else
  {
    device->yield();
  }
}

When your card does not support npot textures all crazy things might happen including green elephants dancing on your desktop

You should try using a pot texture to see if it makes a difference.

I have a Radeon HD 4870, I don't think there are any features it doesn't support. Also, why does it work in fullscreen? Anyway, I will test it.

ATI has several bugs in their NPOT support, so don't really count on it.

ops, almost forgot about this one... works with POT textures.
