Actually, it happens on Windows with GLJPanel and when pbuffers are disabled. The problem comes from the vertical flip of the image by the Screenshot class. Unlike the display method of the GLJPanel, the Screenshot class always performs the flip. In the GLJPanel, before displaying the image, a check is done to know whether the image should be flipped or not. This check obviously lacks in the Screenshot class. ---- Additional Comments From gibe 2009-01-28 06:04:55 ---- Here is a workaround for the bug: ------------------------ // might unecessary flip the image BufferedImage img = Screenshot.readToBufferedImage(getWidth(), getHeight()); // check if it was the case boolean needFlip; try { // raises an exception if hardware acceleration is on needFlip = !((GLContextImpl)GLContext.getCurrent()).offscreenImageNeedsVerticalFlip(); } catch (GLException e) { // hardware acceleration is on needFlip = false; } if (needFlip) { // flip it back ImageUtil.flipImageVertically(img); } ---------------- If you were using Screenshot.writeToFile, use the code above and ImageIO.write(...) instead. --- Bug imported by sgothel@jausoft.com 2010-03-24 07:51 EDT --- This bug was previously known as _bug_ 367 at https://jogl.dev.java.net/bugs/show_bug.cgi?id=367 1858 1 sgothel 2012-09-30 21:11:24 +0200 Root cause is the Windows software renderer, won't fix.
