--- Comment #28 from Maik Qualmann <metzping...@gmail.com> --- I'll take another look at it in the days. But here with me the sharpness looks identical to that of the slideshow viewer. Remember, the GLViewer is optimized for fast image viewing with OpenGL Zoom. Depending on the monitor resolution, the fast preview can also come from the embedded preview of the JPG image. This is by design because it is supposed to be "fast". Therefore I added the possibility to load an original picture with the "o" key. However, this cannot be the standard for the GLViewer because it is too slow. Unlike with a slideshow, we don't have any longer pauses between the images. The OpenGL hardware and drivers can also influence the display. As I said, the GLViewer is intended to "fast" look through the images.
