Steps to Reproduce:

2. Load it to an OpenGL texture

glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_BGR, GL_UNSIGNED_BYTE, buffer);

Actual Results:

Additional Information:
-------------------------------

- Texture will be shown if I change the format in the glTexImage2D call to GL_RGB, but the red and blue channel is switched (GL_RGB.png)

- no Problem by texture wide <=5460 pixel (5460px.png), Problem begin at 5461pixel (5461px.png)
